Math

Math class in Global context

Mathematical functions library.

27 members:

pi float	pi ~ 3.14
pi2 float	pi/2 ~ 1.57
pi4 float	pi/4 ~ 0.78
rnd01 float	random number [0..1)
rndGaussStd float	random number (normal distribution)
seed integer	random seed Random number generator seed. Note: Math.seed influences all future random activity in the simulator, not only Math.rnd01 results.
time float	current time Number of seconds since the Epoch (00:00:00 UTC/GMT, January 1, 1970)
twopi float	2*pi ~ 6.28
abs returns float	absolute value `function abs(float)`
acos returns float	arc cosinus `function acos(float)`
asin returns float	arc sinus `function asin(float)`
atan returns float	arc tangent `function atan(float)`
atan2 returns float	arc tangent of y/x `function atan2(float y, float x)`
cos returns float	cosinus `function cos(float)`
exp returns float	exponent `function exp(float)`
log returns float	logarithm; base = e `function log(float)`
max returns untyped	maximum `function max(untyped, untyped)`
min returns untyped	minimum `function min(untyped, untyped)`
pow returns float	power, a^b `function pow(float a, float b)`
random returns integer	integer random number `function random(integer num)` 0..num-1
rndCustom returns float	random number `function rndCustom(Vector)` the parameter describes the desired random distribution, being a sum of uniform distributions, eg. rndCustom([-10,-1, -1,1, 1,10]) defines 3 uniform distribution intervals [-1,10) [-1,1), [1,10)
rndGauss returns float	random number (selectable std.dev.) `function rndGauss(float center, float stdandard_deviation)` rndGaussStd is rndGauss(0,1)
rndUni returns float	random number (uniform distribution) `function rndUni(float begin, float end)` [begin..end)
sigmoid returns float	sigmoid function = 2/(1+exp(-x))-1 `function sigmoid(float)`
sign returns integer	sign (-1, 0 or 1) `function sign(float)`
sin returns float	sinus `function sin(float)`
sqrt returns float	square root `function sqrt(float)`
