public static bool Approximately (float a, float b);

説明

Compares two floating point values and returns true if they are similar.

Floating point imprecision makes comparing floats using the equals operator inaccurate. For example, (1.0 == 10.0 / 10.0) might not return true every time. Approximately() compares two floats and returns true if they are within a small value (Epsilon) of each other.
