Command-line calculator

Any time you are entering a number, length, point coordinate, or angle, you can use a math formula.

In addition to addition, subtraction, multiplication, division, you can also use parenthesis and math functions.

If you need the number pi (3.14159...), type pi.
When prompted for a point, to get a point 10 units from the origin rotated counter-clockwise 30 degrees, type: 10*sin(30degrees),10*cos(30degrees)
When prompted for any coordinate or length, append any metric or US customary length unit or abbreviation that makes sense in any of the languages Rhino supports. For example:
10m
10meter
10meters
10metros
10metre
10metres
When prompted for any angle value, append any angle unit name makes sense in any of the languages Rhino supports. For example:
30d
30degrees
pi
pi/2radians
100gradians
15d30'22.3450" (arc degrees, arc minutes, arc seconds)
22' (22 arc minutes)
When the number pi (3.14159....) is needed, type pi or the Greek letter π.
You can use formulas like (10*sin(pi/4) + 63.00)/1.234e12+-56.3 (no spaces in formulas).
More generally, a formula can contain:
unary +, unary -,
arithmetic: addition, subtraction, multiplication, division
parentheses
math functions: sin, cos, tan, asin, acos, atan, atan2, ln, log10, exp, sinh, cosh, tanh, pow, sqrt
numbers, including integer-dash-fraction formatted numbers as in 1-3/4 for 1.75
