getRounded(num): number

Avoids cumulative rounding errors only by changing rounding rules when
the fraction part of num is .5 :

• If num's whole number is even, `num` is rounded toward zero.
• If num's whole number is odd, `num` is rounded away from zero.

getRoundedDown(num): number

Behaves same as Math.floor() .

getRoundedUp(num): number

Behaves same as Math.ceil() .

For all 3 functions, num must be a finite number of type 'number'.
