Yet another command line calculator
Authored by: delza on Feb 02, '05 01:27:30PM

Another tip for using Python from the command-line: for short scripts you don't need to start the interactive editor, you can just pass the script to the interpreter with -C, but you will have to print the results explicitly.

For example:

# 2 to the power of 16
python -c "print 2 ** 10"

# hex representation of 1024
python -c "print hex(1024)"

# base-10 representation of 0x400
python -c "print int('0x400', 16)"

# cosine of pi/4
python -c "import math; print math.cos(math.pi * 0.25)"

I presume we've already covered applescript?

osascript -e '3+4/8'
And you can use the Services menu when in most text boxes (incl. TextEdit, Pages, etc) to evaluate any applescript expression.
