Rounds away from zero to. Thus the magnitude of the rounded value is always greater or equal to the magnitude of the input value. In case a 'multiple' is supplied, the value will be rounded to the next multiple of that value hence to an integer value.

Ceiling( x )
Ceiling( x, #multiple )

Numeric value

Ceiling (3.2)	//4
Ceiling (1.5)	//2
Ceiling (-7.7)	//-7, note the difference to RoundUp here

Ceiling (4.2, 3)	//6
Ceiling (1.5, 3)	//3
Ceiling (-7.7, 5)	//-5
