Mathf.Epsilon

Description

A tiny floating point value (Read Only).

The smallest value that a float can have different from zero.

With the following rules:

- anyValue + Epsilon = anyValue
- anyValue - Epsilon = anyValue
- 0 + Epsilon = Epsilon
- 0 - Epsilon = -Epsilon


A value Between any number and Epsilon will result in an arbitrary number due to truncating errors.

See Also: Mathf.Approximately.
