Types

Floating point numbers (“floats”)	Floating point numbers contain all numbers including Integers, and numbers with decimals, for example `15.25`.
Strings	You can enclose strings in double quotes (`"`) or apostrophes (`'`). Variables inside double-quotes are expanded. Strings inside apostrophes are not expanded.
Vectors	Three floating point values. These values can be used to represent positions, directions, normals or colors (RGB or HSV).
Matrix	Sixteen floating point values representing a 3D transformation matrix.

Exponential notation is a concise way of representing large numbers with a minimal amount of digits, for example 3.2e-5 (equivalent to 0.000032).
