Unnecessary cast to float when calling Mathf.Abs
The return type of Math.Abs is float, so explicit cast to float in the return statement of Mathf.Abs is unnecessary and leads to increase execution time
Mathf.Abs:
public static float Abs(float f) { return (float)Math.Abs(f); }
Custom Abs method:
float Abs (float input) { return Math.Abs(input); }
Math.Abs:
public static float Abs (float value);
Steps to reproduce:
1. Open the attached "1372997-sample" project
2. Enter Play mode
3. Observe the Console
Expected result: executing time of Mathf.Abs is taking the approximately same amount of time as the custom Abs method
Actual result: executing Mathf.Abs takes noticeably more time
