CEIL(3) 						   BSD Library Functions Manual 						   CEIL(3)

NAME
ceil -- round to smallest integral value not less than x SYNOPSIS
#include <math.h> double ceil(double x); long double ceill(long double x); float ceilf(float x); DESCRIPTION
The ceil() functions return the smallest integral value greater than or equal to x. SPECIAL VALUES
ceil(+-0) returns +-0. ceil(+-infinity) returns +-infinity. VECTOR OPERATIONS
If you need to apply the ceil() 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 vceilf(vFloat x); void vvceilf(float *y, const float *x, const int *n); void vvceil(double *y, const double *x, const int *n); SEE ALSO
floor(3), round(3), trunc(3), math(3) STANDARDS
The ceil() functions conform to ISO/IEC 9899:2011. BSD

SIN(3)							   BSD Library Functions Manual 						    SIN(3)

NAME
sin -- sine function SYNOPSIS
#include <math.h> double sin(double x); long double sinl(long double x); float sinf(float x); DESCRIPTION
The sin() function computes the sine of x (measured in radians). SPECIAL VALUES
sin(+-0) returns +-0. sin(+-infinity) returns a NaN and raises the "invalid" floating-point exception. VECTOR OPERATIONS
If you need to apply the sin() 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 vsinf(vFloat x); vFloat vsincosf(vFloat x, vFloat *c); void vvsinf(float *y, const float *x, const int *n); void vvsin(double *y, const double *x, const int *n); void vvsincosf(float *s, float *c, const float *x, const int *n); void vvsincos(double *s, double *c, const double *x, const int *n); SEE ALSO
acos(3), asin(3), atan(3), atan2(3), cos(3), cosh(3), sinh(3), tan(3), tanh(3), math(3) STANDARDS
The sin() function conforms to ISO/IEC 9899:2011. BSD
