이 헤더는 numeric 라이브러리의 일부로, 특히 C 객체의 바이트 순서 와 바이트 및 비트 표현 을 다루는 매크로와 함수를 제공합니다.

함수

stdc_first_leading_zero (C23)	최상위 비트부터 시작하여 0 비트의 첫 번째 위치를 찾음 (타입-제네릭 함수 매크로)
stdc_first_leading_one (C23)	최상위 비트부터 시작하여 첫 번째 1 비트의 위치를 찾음 (타입-제네릭 함수 매크로)
stdc_first_trailing_zero (C23)	최하위 비트부터 시작하여 0 비트의 첫 번째 위치를 찾음 (타입-제네릭 함수 매크로)
stdc_first_trailing_one (C23)	최하위 비트부터 시작하여 1 비트의 첫 번째 위치를 찾음 (타입-제네릭 함수 매크로)
stdc_count_zeros (C23)	부호 없는 정수에서 0 비트의 개수를 셉니다 (타입-제네릭 함수 매크로)
stdc_count_ones (C23)	부호 없는 정수에서 1 비트의 개수를 셉니다 (타입-제네릭 함수 매크로)
stdc_has_single_bit (C23)	숫자가 2의 정수 거듭제곱인지 확인합니다 $2$ (타입-제네릭 함수 매크로)
stdc_bit_width (C23)	주어진 값을 표현하는 데 필요한 최소 비트 수를 찾음 (타입-제네릭 함수 매크로)
stdc_bit_floor (C23)	주어진 값보다 크지 않은 가장 큰 2의 정수 거듭제곱을 찾음 (타입-제네릭 함수 매크로)
stdc_bit_ceil (C23)	주어진 값보다 작지 않은 가장 작은 2의 정수 거듭제곱을 찾음 (타입-제네릭 함수 매크로)
매크로 상수
__STDC_ENDIAN_LITTLE__ __STDC_ENDIAN_BIG__ __STDC_ENDIAN_NATIVE__ (C23)	스칼라 타입의 엔디언 방식을 나타냅니다 (매크로 상수)
