NumMoreExtensions on num: Number More: clamp non-negative, isInteger, round half up, truncate decimals, percentage, degrees/radians, etc. Roadmap #311-325.

degreesToRadians(double deg) → double: Converts an angle in degrees (deg) to radians.
digitSum(int n) → int: Returns the sum of the decimal digits of n.
isPowerOfTwo(int n) → bool: Returns true if n is a positive power of two (1, 2, 4, 8, …).
isqrt(int n) → int: Returns the integer square root of n (the floor of its real square root).
nextPowerOfTwo(int n) → int: Returns the smallest power of two greater than or equal to n.
normalizeAngle180(double degrees) → double: Normalizes degrees into the range (-180, 180].
normalizeAngle360(double degrees) → double: Normalizes degrees into the range [0, 360).
radiansToDegrees(double rad) → double: Converts an angle in radians (rad) to degrees.
