All the proposed answers:
- round(x) - round to the closest integer to x
- floor(x) - round to the nearest integer less or equal to x
- ceil(x) - round to the nearest integer greater than or equal to x
- fix(x) - round to the nearest integer towards 0 (floor(x) for x >=0 and ceil(x) for x<=0)
does not convert the number, but only rounds it. Type of the number is still the same. To convert a decimal (double) number to an integer, one needs to use Conversion Functions. Rounding is automatic, but can be chosen explicitly. Examples:
- uint16(1.8) -> 2
- int32(floor(1.8)) -> 1

floor() to round down to nearest integer
ceil() to round up to nearest integer
