-.SH DESCRIPTION
-These functions return the smallest integral value that is not less than
-.IR x .
-.P
-For example,
-.I ceil(0.5)
-is 1.0, and
-.I ceil(\-0.5)
-is 0.0.
-.SH RETURN VALUE
-These functions return the ceiling of
-.IR x .
-.P
-If
-.I x
-is integral, +0, \-0, NaN, or infinite,
-.I x
-itself is returned.
-.SH ERRORS
-No errors occur.
-POSIX.1-2001 documents a range error for overflows, but see NOTES.
-.SH ATTRIBUTES
-For an explanation of the terms used in this section, see
-.BR attributes (7).

-.SH STANDARDS
-C11, POSIX.1-2008.
-.SH HISTORY
-C99, POSIX.1-2001.
-.P
-The variant returning
-.I double
-also conforms to
-SVr4, 4.3BSD, C89.
-.SH NOTES
-SUSv2 and POSIX.1-2001 contain text about overflow (which might set
-.I errno
-to
-.BR ERANGE ,
-or raise an
-.B FE_OVERFLOW
-exception).
-In practice, the result cannot overflow on any current machine,
-so this error-handling stuff is just nonsense.
-.\" The POSIX.1-2001 APPLICATION USAGE SECTION discusses this point.
-(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 127 (respectively, 1023),
-and the number of mantissa bits
-including the implicit bit
-is 24 (respectively, 53).)
-.P
-The integral value returned by these functions may be too large
-to store in an integer type
-.RI ( int ,
-.IR 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.
