sinh, sinhf

Computes the hyperbolic sine of x. A range error occurs if the magnitude of x is too large.

Synopsis

#include <math.h>

double sinh(double x);

float sinhf(float x);

Returns

The hyperbolic sine value.

Example

double x=1.24;

double y;

y=sinh(x);

sprintf

The sprintf function is equivalent to printf, except that the argument s specifies an

array into which the generated output is to be written, rather than to a stream. A null char-

acter is written at the end of the characters written; it is not counted as part of the returned

sum.

Synopsis

#include <stdio.h>

int sprintf(char *s, const char *format, ...);

Returns

The number of characters written in the array, not counting the terminating null character.

Example

int d=51;

char buf [40];

sprintf(buf,"COMPASS/%d",d);

sqrt, sqrtf

Computes the non-negative square root of x. A domain error occurs if the argument is 

negative.
