Built-in math functions

Method Prototype	Description
Abs( value As Double ) As Double	compute the absolute (i.e. unsigned) value of any number
ACos( value As Double ) As Double	compute the arccosine of a number from -1 to 1
ASin( value As Double ) As Double	compute the arcsine of a number from -1 to 1
ATan( value As Double ) As Double	compute the arctangent of any number
ATan2( y As Double, x As Double ) As Double	compute the angle (in radians) between the X axis to the given point (x,y)
Ceil( value As Double ) As Double	find the closest integer greater than or equal to the given value
Cos( value As Double ) As Double	compute the cosine of an angle
Exp( power As Double ) As Double	compute the exponential function, i.e. e raised to the given power
Floor( value As Double ) As Double	find the closest integer less than or equal to the given value
Log( value As Double ) As Double	compute the natural logarithm of a positive number
Max( n1 As Double, ParamArray others As Double ) As Double	find the greatest of two or more numbers
Min( n1 As Double, ParamArray others As Double ) As Double	find the least of two or more numbers
Pow( base As Double, exponent As Double ) As Double	equivalent to base ^ exponent
Rnd As Double	return a uniformly distributed pseudorandom number from 0 to 1 (see also Random)
Round( value As Double ) As Double	round the given number to the nearest integer
Sin( value As Double ) As Double	compute the sine of an angle
Sqrt( value As Double ) As Double	compute the square root of a nonnegative number
Tan( value As Double ) As Double	compute the tangent of an angle

These are the basic math functions built into Yuma. Trigonometric functions all take or return angles in radians, not degrees.

Invalid arguments (such as Log(-1), for example) will result in error values, which if passed through Str display as something like "-NAN(000)".
