Precision Types

Description

There are currently two Precision Types in Shader Graph. Use the options listed in Precision Modes to define a Precision Type for each node.

Precision Types

Name	Description
Half	Medium precision floating point value; generally 16 bits (range of –60000 to +60000, with about 3 decimal digits of precision). Half precision is useful for short vectors, directions, object space positions, and high dynamic range colors.
Float	Highest precision floating point value; generally 32 bits (identical to float in regular programming languages). Full float precision is useful for world space positions, texture coordinates, and scalar computations that involve complex functions such as trigonometry, power, and exponentiation.
