Mathf.Epsilon

説明

ごくわずかな浮動小数点の値を返す（読み取り専用）。

0 との差分を持っている最小の値。

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.

    // to create a function to compare them.
