NAMElrint(), lrintf(), lrintl(), lrintw(), lrintq() — round to nearest long int functions DESCRIPTIONlrint() rounds its argument to the nearest integral value, rounding according to the current rounding direction. lrint() is equivalent to llrint(), except that it rounds to long int instead of long long. USAGETo use these functions, compile either with the default -Ae option or with the -Aa and -D_HPUX_SOURCE options. To use (for Itanium-based systems) lrintw() or lrintq(), compile also with the -fpwidetypes option. Make sure your program includes <math.h>. Link in the math library by specifying -lm on the compiler or linker command line. For more information, see the HP-UX Floating-Point Guide. RETURN VALUEIf the rounded value is outside the range of long int, the numeric result is the maximum or minimum long int value and the invalid floating-point exception is raised. On Itanium-based systems, if the rounded value is outside the range of long int, the numeric result is the minimum long int value. When lrint() raises no other floating-point exception and the result differs from the argument, the function raises the inexact floating-point exception.
