Function atan [src]

Returns the arc-tangent of x. Special Cases: atan(+-0) = +-0 atan(+-inf) = +-pi/2

Prototype

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

Example

 test atan {
    try expect(@as(u32, @bitCast(atan(@as(f32, 0.2)))) == @as(u32, @bitCast(atan32(0.2))));
    try expect(atan(@as(f64, 0.2)) == atan64(0.2));
}

Source

  pub fn atan(x: anytype) @TypeOf(x) {
    const T = @TypeOf(x);
    return switch (T) {
        f32 => atan32(x),
        f64 => atan64(x),
        else => @compileError("atan not implemented for " ++ @typeName(T)),
    };
}
