$Math

The $Math namespace houses mathematical constants and functions that may be useful when writing scripts.

Note:

There are additional mathematical functions available in DeltaScript that are included as part of the standard library.

Constants

PI

$Math.PI

Pi represented as a float.

Note:

The float type in DeltaScript is actually implemented as a double-precision floating point number, and is internally mapped to Java's double primitive type.
