DESCRIPTION

31       These functions calculate the inverse hyperbolic sine of x; that is the
32       value whose hyperbolic sine is x.
33

RETURN VALUE

35       On success, these functions return the inverse hyperbolic sine of x.
36
37       If x is a NaN, a NaN is returned.
38
39       If x is +0 (-0), +0 (-0) is returned.
40
41       If x is positive infinity (negative infinity), positive infinity (nega‐
42       tive infinity) is returned.
43

ERRORS

45       No errors occur.
