A lot of time the discussion has come up do evaluate math on the commandline.
Never did I myself had much need for it but today I realized for a project it would come in handy.
What is the status of this? Can we evaluate math like 25+42 in any way as commandline input already?
To answer my own question:
Command-line calculator Allows entering mathematical notation on the command line in response to prompts for numbers. Type =(...) on the command line to evaluate what is inside the parentheses. The mathematical symbols are + add - subtract * multiply / divide ** exponentiation (raise to the power of) Examples using the Point command: 0,=(3/4+12*2) =(2.4*(8-2)),=(2.5*2) =(sqrt(8)-6),0,0 The math module in Python is also supported which means you have access to functions like sin, cos, tan, pi, sqrt, etc. These are listed at http://docs.python.org/library/math.html.
