tanhf
Description:
Include:
Prototype:
Argument:
Return Value:
Remarks:
Example:
Calculates the hyperbolic tangent function of a single precision
floating-point value.
<math.h>
float tanhf (float x);
x
Returns the hyperbolic tangent of x in the ranges of -1 to 1 inclusive.
No domain or range error will occur.
#include <math.h>
#include <stdio.h> /* for printf */
int main(void)
{
}
Output:
The hyperbolic tangent of -1.000000 is -0.761594
The hyperbolic tangent of 0.000000 is 0.000000
float x, y;
x = -1.0F;
y = tanhf (x);
printf("The hyperbolic tangent of %f is %f\n\n",
x = 0.0F;
y = tanhf (x);
printf("The hyperbolic tangent of %f is %f\n\n",
value for which to return the hyperbolic tangent
x, y);
x, y);
