Math FunctionsFor versions of Python prior to 3.0, Python performs integer division with truncation, so that 3/4 is 0, not 0.75. This is inconvenient when doing scientific computations, and can lead to hardtofind bugs in programs. In the GlowScript environment, where VPython code is compiled to JavaScript, 3/4 is always 0.75. The following math functions are provided: abs(x) Many of the quantities above are short forms of the JavaScript functions Math.abs(x), Math.sqrt(x), etc. Here are details of the factorial and combin functions. There are functions for converting between degrees and radians, where there are 2*pi radians in 360 degrees: radians(360) # equal to 2*pi See JavaScript documentation on the Date object which provides methods for determining the current day etc. Here is a way to determine elapsed time in seconds, with microsecond accuracy, using the clock() function that is also available in the standard Python "time" module. The displayed text is approximately 1.5: t1 = clock() There is also a function msclock() which gives the time in milliseconds instead of seconds. You can use LaTeX to display mathematical expressions on the page.
