Function tanh [src]

Returns the hyperbolic tangent of x. Special Cases: tanh(+-0) = +-0 tanh(+-inf) = +-1 tanh(nan) = nan

Prototype

pub fn tanh(x: anytype) @TypeOf(x)

Example

 test tanh {
    try expect(tanh(@as(f32, 1.5)) == tanh32(1.5));
    try expect(tanh(@as(f64, 1.5)) == tanh64(1.5));
}

Source

  pub fn tanh(x: anytype) @TypeOf(x) {
    const T = @TypeOf(x);
    return switch (T) {
        f32 => tanh32(x),
        f64 => tanh64(x),
        else => @compileError("tanh not implemented for " ++ @typeName(T)),
    };
}
