Вывести все трехзначные числа, сумма цифр которого равна А и число кратно В - C (СИ) - Ответ 3031106

NAME
floor, floorf, floorl - largest integral value not greater than argument

SYNOPSIS
#include <math.h>

double floor(double x);
float floorf(float x);
long double floorl(long double x);

Link with -lm.

Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

floorf(), floorl():
_BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 600 || _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L;
or cc -std=c99

DESCRIPTION
These functions return the largest integral value that is not greater than x.

For example, floor(0.5) is 0.0, and floor(-0.5) is -1.0.

RETURN VALUE
These functions return the floor of x.

If x is integral, +0, -0, NaN, or an infinity, x itself is returned.

ERRORS
No errors occur. POSIX.1-2001 documents a range error for overflows, but see NOTES.

CONFORMING TO
C99, POSIX.1-2001. The variant returning double also conforms to SVr4, 4.3BSD, C89.

NOTES
SUSv2 and POSIX.1-2001 contain text about overflow (which might set errno to ERANGE, or raise an FE_OVERFLOW exception). In practice, the
result cannot overflow on any current machine, so this error-handling stuff is just nonsense. (More precisely, overflow can happen only
when the maximum value of the exponent is smaller than the number of mantissa bits. For the IEEE-754 standard 32-bit and 64-bit floating-
point numbers the maximum value of the exponent is 128 (respectively, 1024), and the number of mantissa bits is 24 (respectively, 53).)

NAME
ceil, ceilf, ceill - ceiling function: smallest integral value not less than argument

SYNOPSIS
#include <math.h>

double ceil(double x);
float ceilf(float x);
long double ceill(long double x);

Link with -lm.

Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

ceilf(), ceill():
_BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 600 || _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L;
or cc -std=c99

DESCRIPTION
These functions return the smallest integral value that is not less than x.

For example, ceil(0.5) is 1.0, and ceil(-0.5) is 0.0.

RETURN VALUE
These functions return the ceiling of x.

If x is integral, +0, -0, NaN, or infinite, x itself is returned.

The integral value returned by these functions may be too large to store in an integer type (int, long, etc.). To avoid an overflow,
which will produce undefined results, an application should perform a range check on the returned value before assigning it to an integer
type.
