pyBigParser 2.2

Math parser for simple and compound strings math expressions evaluations

pyBigParser

pyBigParser provides classes for parsing long and complex math expresions. You might find it most useful for tasks involving evaluating from single functions to compounds functions. Typical usage often looks like this:

from pybigparser import evaluator

mybig = evaluator.bigFunction()
mybig.setFunction("x**2+2*y")
mybig.addSub("x", "24+6*c")
mybig.addSub("y", "25 / d")
mybig.addSub("c", "1")
mybig.addSub("d", "4")

mybig.evaluate()

mybig.getSubValue("x")
mybig.getSubValue("y")

Supported Functions

• cos, sin, abs, log10, log, exp,
• tan, pi, e

Versions

• 1.3 - It saves the values for each sub-function.
• 1.5 - Fixed OverFlow Error with Exp function

Warnings

• The variables e and pi are reserved for the evaluator
• Exceptions for iterative variables are not supported
