Code example:

DMath.abs(a);

Math formula:

$$Symbol: |a|$$

$$x = \begin{cases} a & \text{if } a > 0 \ 0 & \text{otherwise} \end{cases}$$

$$|-3| = 3$$

$$|2| = 2$$

a - { Value to determine the absolute value to be returned. }

Returns the absolute value of a scalar or vector.

The absolute value, or modulus, represents the distance from a scalar to 0

abs implementation for a float scalar.

float abs(float a)
{
	return max(-a, a)
}

Abs is extremely inexpensive in coding.
