Function atanh [src]

Alias for std.math.atanh.atanh

Returns the hyperbolic arc-tangent of x. Special Cases: atanh(+-1) = +-inf with signal atanh(x) = nan if |x| > 1 with signal atanh(nan) = nan

Prototype

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

Example

 test atanh {
    try expect(atanh(@as(f32, 0.0)) == atanh_32(0.0));
    try expect(atanh(@as(f64, 0.0)) == atanh_64(0.0));
}

Source

  pub fn atanh(x: anytype) @TypeOf(x) {
    const T = @TypeOf(x);
    return switch (T) {
        f32 => atanh_32(x),
        f64 => atanh_64(x),
        else => @compileError("atanh not implemented for " ++ @typeName(T)),
    };
