# ceilf(3) [osx man page]

```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);

floor(3), round(3), trunc(3), math(3)

STANDARDS
The ceil() functions conform to ISO/IEC 9899:2011.

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);
