ceil(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.

```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);

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.

math.h: float ceilf(float x)

Good morning, I'm testing the use of ceilf: /*Filename: str.c*/ #include <stdio.h> #include <math.h> int main (void) { float ceilf(float x); int dev=3, result=0; float tmp = 3.444f; printf("Result: %f\n",ceilf(tmp)); return 0; }

How to get the ceiling value for floating numbers?

Dear guys; How can I get the ceiling value of any floating number using shell or awk scripts or functions. Example:- old values "7.2" or "7.8" or "7.5" --->>> ceiling function ---->>> new value "8". BR

CEILING and FLOOR functions

Hi all, Does anyone know how to simulate a ceiling or floor function in UNIX? OS is Solaris. I tried the suggestion from an old forum but it is giving me error as below: server01/tmp\$: echo "7.2" | awk '{printf("%d\n",\$0+=\$0<0?0:0.999)}' awk: syntax error near line 1 awk: illegal...

Ceil not working as function in awk statement

Hi, I have the following code in which i am trying to find ceil of 10th & 11th fields. For finding ceil i have a function in the awk statement. When i test it for some values say on command line it gives correct response(say \$10=0 & \$11=750). But when the same value occurs in a file having more 3...
