Mathf.Approximately

Description

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.

    void Example() {
        if (Mathf.Approximately(1.0F, 10.0F / 10.0F))
            print("The values are approximately the same");
        
    }
