- the #eval directive is similar to the #calc directive, but for evaluating
string expressions into scalar values. It uses an internal parser for
the evaluation instead of dynamic code compilation. This can make it
more suitable for 'quick' evaluations.
The evaluation supports the following:
- operations: - + * /
- functions: exp, log, log10, pow, sqrt, cbrt, sqr, mag, magSqr
- trigonometric: sin, cos, tan, asin, acos, atan, atan2, hypot
- hyperbolic: sinh, cosh, tanh
- conversions: degToRad, radToDeg
- constants: pi()
- misc: rand(), rand(seed)
