Hi Kari,

When rounding floating point numbers in C and other languages you have many options, like round down, round up, round to the nearest integer, etc. In the library math.h in C you can find:
floor: round down.
ceil: round up.
round: round to nearest integer.

You can find an explanation of these functions, as well as code examples in this site: http://www.cplusplus.com/reference/cmath/round/

Good coding.
