The modules for the floating point arithmetic. The Math module has methods and modules methods of the same definitions in same names.
Example:
pi = Math.atan2(1, 1) * 4; include Math pi2 = atan2(1, 1)
atan2(x, y)
Returns the arc tangent of the two variable x and y, which is between -PI and PI.
cos(x)
sin(x)
tan(x)
Returns the cosine, sine, tangent, respectively, of x, where x is given in radians, which is between -1 and 1.
exp(x)
Returns the value of e raised to the power of x.
log(x)
Returns the natural logarithm of x.
log10(x)
Returns the base-10 logarithm of x.
sqrt(x)
Returns non-negative square root of x. It raises an exception, if x is negative.
The pi.
