Return Value
A double in the range -1 to +1.
COSH, SINH, TANH
Synopsis
#include <math.h>
double cosh (double f)
double sinh (double f)
double tanh (double f)
Description
These functions are the implement hyperbolic equivalents of the trigonometric
functions; cos(), sin() and tan().
Example
#include <stdio.h>
#include <math.h>
void
main (void)
{
printf(“%f\n”, cosh(1.5));
printf(“%f\n”, sinh(1.5));
printf(“%f\n”, tanh(1.5));
}
Return Value
The function cosh() returns the hyperbolic cosine value.
The function
sinh() returns the hyperbolic sine value.
The function
tanh() returns the hyperbolic tangent value.
CPUTS
Synopsis
#include <conio.h>
void cputs (const char * s)
Description
The cputs() function writes its argument string to the console, outputting carriage
returns before each newline in the string. It calls putch() repeatedly. On a hosted sys-
tem
cputs() differs from puts() in that it writes to the console directly, rather than
using file I/O. In an embedded system
cputs() and puts() are equivalent.
