These will not be relevant to many games at all, but are available as a consequence of the .NET framework Quest 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 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

The following functions all take a floating point parameter and return an integer.

• Ceiling
• Floor
• Round
• Truncate
• Sign

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

• Max
• Min
