This header is part of thenumeric library, in particular, it provides macros and functions to work with thebyte ordering andbyte and bit representation of C objects.
Functions | |

(C23) | counts the number of consecutive1 bits, starting from the most significant bit (type-generic function macro)[edit] |
(C23) | counts the number of consecutive0 bits, starting from the least significant bit (type-generic function macro)[edit] |
(C23) | counts the number of consecutive1 bits, starting from the least significant bit (type-generic function macro)[edit] |
| finds the first position of0 bit, starting from the most significant bit (type-generic function macro)[edit] | |
| finds the first position of1 bit, starting from the most significant bit (type-generic function macro)[edit] | |
| finds the first position of0 bit, starting from the least significant bit (type-generic function macro)[edit] | |
| finds the first position of1 bit, starting from the least significant bit (type-generic function macro)[edit] | |
(C23) | counts the number of0 bits in an unsigned integer (type-generic function macro)[edit] |
(C23) | counts the number of1 bits in an unsigned integer (type-generic function macro)[edit] |
