Returns:

Example:

 MathUtil.map(10, 0, 100, 0, 50);
 // 5

Returns the number that corresponds to the percentage in a given range. Example: percent = 0.5 range 10 to 20 // outputs 15

Parameters:

• percent Number
• min Number
• max Number

Returns:

Example:

 MathUtil.percentToRange(0.5, 10, 20);
 // 15

Converts radians to degrees.

Parameters:

• radians Number

Returns:

Example:

 MathUtil.radiansToDegrees(1.5707963267948966);
 // 90
 MathUtil.radiansToDegrees(3.141592653589793);
 // 180

Returns a random number between min and max.

Parameters:

• min Number
• max Number
• [wholeNumber=true] Number optional

Returns:

Example:

Returns the percentage of a number in a given range. Example: num = 15 range 10 to 20 // outputs 0.5

Parameters:

• num Number
• min Number
• max Number
• constrainMin Boolean

  Returns 0 if num < min.

• constrainMax Boolean

  Returns 1 if num > max.

Returns:

Example:

 MathUtil.rangeToPercent(15, 10, 20);
 // 0.5

Returns 1 if the value is >= 0. Returns -1 if the value is < 0.

Parameters:
