NAME
trunc -- truncate to integer value
SYNOPSIS
#include <math.h> double trunc(double x); long double truncl(long double x); float truncf(float x);
DESCRIPTION
The trunc() functions return the integral value nearest to but no larger in magnitude than x.
SPECIAL VALUES
trunc(+-0) returns +-0. trunc(+-infinity) returns +-infinity.
VECTOR OPERATIONS
If you need to apply the trunc() function to SIMD vectors or arrays, using the following functions provided by the Accelerate.framework may give significantly better performance: #include <Accelerate/Accelerate.h> vFloat vintf(vFloat x); void vvintf(float *y, const float *x, const int *n); void vvint(double *y, const double *x, const int *n);
SEE ALSO
ceil(3), floor(3), round(3), math(3)
STANDARDS
The trunc() functions conform to ISO/IEC 9899:2011.
