svml128_tanh_f?

Compute the hyperbolic tangent of the input vector.

Interface Definition

C interface:

float32x4_t svml128_tanh_f32(float32x4_t src);

float64x2_t svml128_tanh_f64(float64x2_t src);

Parameters

Parameter	Type	Description	Input/Output
src	For svml128_tanh_f32, src is of single-precision floating-point type. For svml128_tanh_f64, src is of double-precision floating-point type.	Floating-point value of the input vector	Input

Return Value

The hyperbolic tangent y of the radian angle x is returned. y ∈ [-1, +1].
If the input is +0, the return value is +0.
If the input is -0, the return value is -0.
If the input is ±∞, the return value is ±1.
If the input is NaN, the return value is NaN.

Dependencies

Examples

C interface:

    float32x4_t src = {0.0f, 2.0f, INFINITY, NAN};
    float32x4_t dst = svml128_tanh_f32(src);
    printf("%.15g  %.15g  %.15g  %.15g\n", dst[0], dst[1], dst[2], dst[3]); 
    /**
     *  Output dst:
     *     0  0.964027580075817  1  -nan
     *
