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?

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.

Hi Willem, if I am working in inches, can I use feet in the command line? Example I am after would be( select line use both sides type 26â€™/2 and it gives me a line 13â€™ each side from starting point) while I am asking,can fractions work as well in this manner? Say, 23/32â€ť divided by 2? Thanks ,Mark

I wish for an option to type â€ś+3â€ť to get the line to be 3 units longer than the snapâ€¦ would that be possible to implement? Or of course add a â€ś-3â€ť to make it 3 units shorter or even â€śx3â€ť and â€ś/3â€ť to get multiplications and fractions.
(imagined example:)
