Function asinh [src]

Returns the hyperbolic arc-sine of z.

Prototype

pub fn asinh(z: anytype) Complex(@TypeOf(z.re, z.im))

Example

 test asinh {
    const epsilon = math.floatEps(f32);
    const a = Complex(f32).init(5, 3);
    const c = asinh(a);

    try testing.expectApproxEqAbs(2.4598298, c.re, epsilon);
    try testing.expectApproxEqAbs(0.5339993, c.im, epsilon);
}
