FloatingPointFormatStyle.Percent is inaccurate for Float16 and Float32 values.

I'm not sure this is solvable on my end. Decimal and Double seem OK.

func testFloat16() {
    let value  = 1.23 as Float16
    let locale = Locale(identifier: "en_US")
    let result = FloatingPointFormatStyle<Float16>.Percent(locale: locale).format(value)
    XCTAssertEqual(result, "123.046875%")
}

func testFloat32() {
    let value  = 1.23 as Float32
    let locale = Locale(identifier: "en_US")
    let result = FloatingPointFormatStyle<Float32>.Percent(locale: locale).format(value)
    XCTAssertEqual(result, "123.000002%")
}

Will probably limit the percent style to Decimal and Double.
