asinh(3m) asinh(3m) Name asinh, acosh, atanh - inverse hyperbolic functions Syntax #include <math.h> double asinh(x) double x; double acosh(x) double x; double atanh(x) double x; Description The and functions compute the designated inverse hyperbolic functions for real arguments. Errors Because of Roundoff, Etc. These functions inherit much of their error from the function. Diagnostics The function returns the default quiet NaN if the argument is less than one. The function returns the default quiet NaN if the argument has an absolute value greater than or equal to one. See Also exp(3m), math(3m) RISC asinh(3m)

asinh, asinhf, asinhl - inverse hyperbolic sine functions SYNOPSIS
cc [ flag... ] file... -lm [ library... ] #include <math.h> double asinh(double x); float asinhf(float x); long double asinhl(long double x); DESCRIPTION
These functions compute the inverse hyperbolic sine of their argument x. RETURN VALUES
Upon successful completion, these functions return the inverse hyperbolic sine of their argument. If x is NaN, NaN is returned. If x is +-0 or +-Inf, x is returned. ERRORS
No errors are defined. ATTRIBUTES
