math.floor and rounding

[Jose <jmalv04@...>]

Hi,

I want to round numbers with two decimal digits.

I use  math.floor( n * 100 )  but sometimes I have situations like:

n = 10.20
math.floor( n * 100 ) --> 1019

My current solution is to always add 0.001 to n, but is this the right
approach ?

thanks
