Integer.valueOf Arabic number works fine but Float.valueOf the same number gives NumberFormatException

Ali :

Using Arabic number Integer.valueOf("۱") returns integer 1 but Float.valueOf("۱") or Float.parseFloat("۱") throws NumberFormatException while it won't throw any exceptions if you use English number Float.valueOf("1"), is it a bug in java or there's some explanation?

How can I parse such a number?

I'm working in android environment;

Eng.Fouad :

It seems that Float.parseFloat() does not support Eastern-Arabic numbers. Alternatively, you can use NumberFormat class:

Locale EASTERN_ARABIC_NUMBERS_LOCALE = new Locale.Builder()
                                                 .setLanguage("ar")
                                                 .setExtension('u', "nu-arab")
                                                 .build();
float f = NumberFormat.getInstance(EASTERN_ARABIC_NUMBERS_LOCALE)
                      .parse("۱٫۵")
                      .floatValue();
System.out.println(f);

OUTPUT:

1.5
