Mathsfont For Thought

Welcome to Thought Quotes. The quotes given here prove beyond doubt that it is thought that creates, and that thought precedes action. It is now universally recognised that destiny, good luck, bad luck, fortune, misfortune, etc. Are all euphemisms for 'result of thinking'.

  3. In What Is Thought? Eric Baum proposes a computational explanation of thought. Just as Erwin Schrodinger in his classic 1944 work What Is Life? Argued ten years before the discovery of DNA that life must be explainable at a fundamental level by physics and chemistry, Baum contends that the present-day inability of computer science to explain thought and meaning is no reason to doubt there can.

On this site you will find all sorts of things related to Mathematics and its teaching. There will be thoughts and

ideas posted on a semi regular basis. There will be resources that I have written and used as a Maths teacher at various times over the last 30 years. The more interesting of these ideas and resources will come from a view of the subject and of teaching the subject that is a little different to the dominant view of our times. This may strike a chord with you or it may challenge and provoke you to look at things differently. The aim is that you find the site and the resources fun, different from what you might normally see and useful.

Using format strings in Python I can easily print a number in 'scientific notation', e.g.

What is the simplest way to format the number in LaTeX format, i.e. 1times10^{+09}?

The siunitx LaTeX package solves this for you by allowing you to use the python float value directly without resorting to parsing the resulting string and turning it into valid LaTeX.

When the LaTeX document is compiled, the above code will be turned into . As andybuckley points out in the comments, the plus sign might not be accepted by siunitx (I've not tested it), so it may be necessary to do a .repace('+', ') on the result.

If using siunitx is somehow off the table, write a custom function like this:


1.5e-10 style scientific notation looks ugly in LaTeX math mode , Notebook sets MathJax up automatically, so no idea what packages they use). Context: floating point numbers and numerical programming. For Then if -4 <= exp < p, the number is formatted with presentation type ‘f’ and precision p-1-exp. Otherwise, the number is formatted with presentation type ‘e’ and precision p-1. In both cases insignificant trailing zeros are removed from the significand, and the decimal point is also removed if there are no remaining digits following it.

You can write a frexp10 function:

Formatting in LaTeX style is then:

Writing mathematical expressions, You can use a subset TeX markup in any matplotlib text string by placing it Fractions, binomials, and stacked numbers can be created with the This is useful, for example, to use the same font as regular non-math text for math text, by setting it to regular . Download Python source code: $ python 12.30 12.30000 The output shows the number having two and five decimal places. Python f-string format width. The width specifier sets the width of the value. The value may be filled with spaces or other characters if the value is shorter than the specified width.

Install num2tex:

and use it as so:

num2tex inherits from str so the format function can be used in the same way.

You can also change the format of the exponent by using num2tex.configure() (adding this in response to @Matt's comment).

As of now this is undocumented in the GitHub, I'll try to change this soon!

Disclaimer: After using (and upvoting) Lauritz V. Thaulow's answer for a while (for Jupyter, Matplotlib etc.) I thought it would be better for my workflow to write a simple Python module, so I created num2tex on GitHub and registered it on PyPI. I would love to get some feedback on how to make it more useful.

Python string format examples, Decimal-point alignment is accomplished by fixing the field width, which is set by placing a number before the decimal point in the format string. We can also write float point number using scientific notation. The numbers written in the form a x 10^b is known as scientific notation. Scientific notation is quite useful for writing very small or very large numbers. For example, float 0.000000123 can be written succinctly in Scientific notation as 1.23 x 10^-7. Python uses special syntax to

LaTeX - Mathematical Python, Jupyter notebook recognizes LaTeX code written in markdown cells and renders the symbols in the browser using the MathJax JavaScript library. Write LaTeX code to display the Prime Number Theorem. lim x → ∞ π ( x ) x log ⁡ ( x ) = 1. The siunitx LaTeX package solves this for you by allowing you to use the python float value directly without resorting to parsing the resulting string and turning it into valid LaTeX. >>> print ' um{{{0:.2g}}}'.format(1e9) um{1e+09} When the LaTeX document is compiled, the above code will be turned into .

Data Simplification: Taming Information With Open Source Tools, Data scientists should familiarize themselves with LaTeX formula notation. The following short python script takes the sample size formula, in ascii notation, Before Python 3.6, you had two main ways of embedding Python expressions inside string literals for formatting: %-formatting and str.format(). You’re about to see how to use them and what their limitations are. Option #1: %-formatting. This is the OG of Python formatting and has been in the language since the very beginning.

Complex text formatting in Matplotlib using LaTeX, To create complex text formatting in Matplotlib we have to use LaTeX. Everything was tested on Ubuntu 14.04 LTS and Python 3. At the moment the Axis (ie the numbers along the X and Y axis) will be in the default sans-serif font: Consequently, I define the maths font using the unicode-math package. If True, format the number according to the current locale. This affects things such as the character used for the decimal separator. If False, use C-style (English) formatting. The default setting is controlled by the axes.formatter.use_locale rcparam. useMathText: If True, render the offset and scientific notation in mathtext

  • I don't think 1^{+09} is quite the output you want, but anyway.
  • True, of course I meant 10^{+09}
  • Nice solution! This does what's asked for, however it's not normal to include a + sign or leading zero in the exponent when formatting for mathematical correctness (cf. the siunitx output above). Also, due to the times command it's a good idea to use a raw ('r') string. These can be done by replacing the first return with: parts = float_str.split('e'); return r'{0} times 10^{{{1}}}'.format(parts[0], int(parts[1])) (Hope that's understandable: SO doesn't code-format in comments!)
  • @andybuckley Thanks for the feedback! I've corrected my answer.
  • I'm also not sure what input siunitx handles, just that its output is in the normal mathematical format without an explicit plus sign or leading 0 in the exponent. My bit of inline code in the comment above is (sadly) the most elegant way that I could think of to map a cast-to-int on the exponent... maybe there is something funky in itertools for such things but hopefully it's clear enough this way!
  • @andybuckley If we map both the exponent and the base to int (and there's no reason not to, as far as I know), we can make it more elegant. See above. :)
  • Erm, what happens to `latex_float(1.234e9) in that case? Or have I missed something obvious?! Obviously the mantissa-as-int works for the specific case of 1e9 :-)
  • The package you offer and the examples on GitHub page are infinitely useful! Cheers mate. :)
  • Would be nice if you found some times to implement the cdot 10^{p} option. :)
  • @Matt it already has this feature, I just hadn't documented it :) See my edited answer for how to do it with cdot
  • I'm afraid there is a slight bug in the package. Quick example: num2tex(100000,precision=1) will yield $times 10^5$, omitting the '1'. it will happen for any $10^n$ with precision $leq n+1$ (but not for $a.10^n$ if $aneq 1$).
