Mathematical functions

These will not be relevant to many games at all, but are available as a consequence of the .NET framework Quest Viva is built on. They are included here for completeness; if you need them, you will know what they do. There is no further documentation.

Quest Viva has e and pi as built-in constants.

These all take a single floating point number, and return the corresponding floating point number. Note that the trigonometric functions use radians rather than degrees.

Abs
Acos
Asin
Atan
Cos
Exp
Log
Log10
Sin
Sinh
Sqrt
Tan
Tanh

These take a floating point parameter and return a whole number, but still as a floating point value - TypeOf(Floor(2.9)) is double, not int. If you need an int, use cast(Floor(2.9), "int"); ToInt only accepts strings. See Values and types.

Ceiling
Floor
Round
Truncate

Round rounds half to even, so Round(2.5) is 2 and Round(3.5) is 4.

This one takes a floating point parameter and returns an int:

Sign

These two functions take two parameters, and can be used with either floating point or integers, and return the same type.
