Prototype

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

Example

 test asin {
    try expect(asin(@as(f32, 0.0)) == asin32(0.0));
    try expect(asin(@as(f64, 0.0)) == asin64(0.0));
}

Source

  pub fn asin(x: anytype) @TypeOf(x) {
    const T = @TypeOf(x);
    return switch (T) {
        f32 => asin32(x),
        f64 => asin64(x),
        else => @compileError("asin not implemented for " ++ @typeName(T)),
    };
}
