Mathf.Epsilon

static var Epsilon : float

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.

JavaScripts

// Compares two floating point numbers and return true if they are the same number.
// See also Mathf.Approximately, which compares floating point numbers so you dont have
// to create a function to compare them.

if(a >= b-Mathf.Epsilon && a <= b + Mathf.Epsilon)
return true;
