How do I find the next multiple of 10 of any integer?

Question

Dynamic integer will be any number from 0 to 150.

i.e. - number returns 41, need to return 50. If number is 10 need to return 10. Number is 1 need to return 10.

Answer 1

How about using integer math:

N=41
N+=9   // Add 9 first to ensure rounding.
N/=10  // Drops the ones place
N*=10  // Puts the ones place back with a zero
