Math.Ceil Function equivalent

Hi all,

I am after an equivalent Math.ceiling function for Decimal/Double/Real numbers in AX 2012 X++ programming. I would like to round up to the the next whole Decimal but can't seem to get the desired outcome using decRound(Number, 0) or  round(Number, 1).

For example if Number is 1.10 I want the output to be 2

Please help! Thanks.
