sinhf(3) Guardian Native C Library Calls Reference Manual
NAME
sinhf - Computes the hyperbolic sine function for a float value
LIBRARY
H-series and J-series native Guardian processes: $SYSTEM.ZDLLnnn.ZCREDLL
32-bit H-series and J-series OSS processes: /G/system/zdllnnn/zcredll
64-bit H-series and J-series OSS processes: /G/system/zdllnnn/ycredll
SYNOPSIS
#include <math.h>
float sinhf(
float x);
PARAMETERS
x Is the float value for which the hyperbolic sine function is to be computed.
DESCRIPTION
The sinhf() function is a float version of the sinh( ) function; it takes a float argument and returns
a float result.
The sinhf() function computes the hyperbolic sine of x.
NOTES
This function supports both IEEE Std 754-1985 floating-point and Tandem floating-point values
in the native environment. IEEE values can include NaN and infinity, and the sign of 0.0 (zero)
can be either positive or negative. Refer to the fp_class(3) reference page for a description of
IEEE value classes.
Guardian functions are available to convert between floating-point formats. Refer to the Guar-
dian Programmer’s Guide for a discussion of floating-point conversions.
RETURN VALUES
The sinhf() function returns the hyperbolic sine of its parameter.
For IEEE floating-point values, if the value of x is NaN, NaN is returned. If the value of x is
positive infinity, positive infinity is returned. If the value of x is negative infinity, negative
infinity is returned.
If the result would cause overflow, positive or negative HUGE_VALF is returned (depending on
the sign of the value of x) and errno is set to [ERANGE]. If the result would cause underflow,
0.0 (zero) is returned.
ERRORS
If any of the following conditions occurs, the sinhf() function sets errno to the corresponding
value:
[ERANGE] The result would cause an overflow.
