works with fractions like 1/3.5
This function defines a command line calculator that handles everything pythons math module can handle, e.g. trigonometric functions, sqrt, log, erf, ... (see http://docs.python.org/library/math.html). It even knows about the constants pi and e. Show Sample Output
This opens a python command line. You can use math and random and float-division is enabled (without appending .0 to integers). I just don't know how to specify a standard precision.
use python as calculator, press ctrl+d to exit reminder: when doing factions add atleast one decimal number like so 22.0/7 or 22/7.0 Show Sample Output
This is an "argument calculator" funktion. The precision is set to 4 and you can use dot (.) or comma (,) as decimal mark (which is great for german users with a comma on the numpad).
Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
