cpik supports the following numeric data types:
cpik type | representable values | constant suffix |
char |
[-128..+127] | none |
unsigned char |
[0..255] | none |
int |
[-128..+127] | none |
unsigned int |
[0..255] | none |
long |
[-32768..32767] | L or l |
unsigned long |
[0..65535] | UL or ul |
long long |
[-2147483648..2147483647] | LL or ll |
unsigned long long |
[0..4294967295] | ULL or ull |
float |
[
![]() ![]() |
optional F or f |
unsigned bit field | depends on field size | none |
signed bit field | depends on field size | none |
Signed integers are represented in 2's complement. Floating point support (float) is compliant with the IEEE 754 standard. As stated by the standard, the precision is 6 or 7 decimal digit, depending on the situation. The floating point library is fully written in assembly language, so it is likely to be fast.
