Function Documentation

atanhf()

float atanhf

(

float

x

)

Compute area hyperbolic tangent.

The atanhf functions compute the arc hyperbolic tangent of x. A domain error occurs for arguments not in the interval [−1, +1]. A pole error may occur if the argument equals −1 or +1.

Parameters

x	Value whose area hyperbolic tangent is computed, in the interval [-1,+1].

Returns

The atanhf functions return artanh x.
