uint8() "saturates" any value above 255 to become 255.
uint16() "saturates" any value above 65535 to become 65535.
uint32() and uint64() exist but the graphics routines cannot display them. Hardly any of the image file format support writing uint64.
Do you need something of integer data type, or do you just need values that are arithmetically integer? fix() and floor() and ceil() can remove fractions but do not produce an integer datatype.
