Function Documentation

float tanhsp_c

(

float

a

)

Description:

The tanhsp function returns the hyperbolic tangent function of a real floating-point argument a. If |a| is larger than 9 the hyperbolic tangent function reaches a maximum of |1.0| for single-precision.

Parameters:

[in]

a

= Input float

Returns:

Resultant float

Special Cases:

• If a > 9.0, then the return value is 1.0 (maximum output for the hyperbolic tangent).
• If a < -9.0, then the return value is 1.0.
• If a is NaN, the return value is NaN.

• tanhsp_v

Implementation Notes:

• The code supports both big and little endian modes.
