Description

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。

以下のルール:

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


ある数とイプシロンの間の値は、端数処理による誤差のために 任意の数になります。

// 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.
