IntlChar::digit — Get the decimal digit value of a code point for a given radix

Description

public static IntlChar::digit ( string $codepoint [, int $radix = 10 ] ) : int

Returns the decimal digit value of the code point in the specified radix.

If the radix is not in the range 2<=radix<=36 or if the value of codepoint is not a valid digit in the specified radix, FALSE is returned. A character is a valid digit if at least one of the following is true:

  • The character has a decimal digit value. Such characters have the general category "Nd" (decimal digit numbers) and a Numeric_Type of Decimal. In this case the value is the character's decimal digit value.
  • The character is one of the uppercase Latin letters 'A' through 'Z'. In this case the value is c-'A'+10.
  • The character is one of the lowercase Latin letters 'a' through 'z'. In this case the value is ch-'a'+10.
  • Latin letters from both the ASCII range (0061..007A, 0041..005A) as well as from the Fullwidth ASCII range (FF41..FF5A, FF21..FF3A) are recognized.
