Hex

Returns the hexadecimal of the given number

Syntax
   Declare Function Hex ( ByVal number As UByte ) As String
   Declare Function Hex ( ByVal number As UShort ) As String
   Declare Function Hex ( ByVal number As ULong ) As String
   Declare Function Hex ( ByVal number As ULongInt ) As String
   Declare Function Hex ( ByVal number As Const Any Ptr ) As String

   Declare Function Hex ( ByVal number As UByte, ByVal digits As Long ) As 
   String
   Declare Function Hex ( ByVal number As UShort, ByVal digits As Long ) As 
   String
   Declare Function Hex ( ByVal number As ULong, ByVal digits As Long ) As 
   String
   Declare Function Hex ( ByVal number As ULongInt, ByVal digits As Long ) 
   As String
   Declare Function Hex ( ByVal number As Const Any Ptr, ByVal digits As 
   Long ) As String

Usage
   result = Hex[$]( number [, digits ] )

Parameters
   number
      A number or expression evaluating to a number.  A floating-point 
      number will be converted to a LongInt.
   digits
      Optional number of digits to return.

Return Value
   A String containing the unsigned hexadecimal representation of number.

Description
   Returns the unsigned hexadecimal string representation of the integer 
   number. Hexadecimal digits range from 0-9, or A-F.

   If you specify digits > 0, the result string will be exactly that 
   length.  It will be truncated or padded with zeros on the left, if 
   necessary.

   The length of the string will not go longer than the maximum number of 
   digits required for the type of number (8 for a Long, 16 for a LongInt).

   If you want to do the opposite, i.e. convert a hexadecimal string back 
   into a number, the easiest way to do it is to prepend the string with 
   "&H", and convert it to an integer type, using a function like CInt, 
   similarly to a normal numeric string.  E.g. CInt("&HFF")

Example
   '54321 is D431 in hex
   Print Hex(54321)
   Print Hex(54321, 2)
   Print Hex(54321, 5)

   will produce the output:

   D431
   31
   0D431

Dialect Differences
   * The string type suffix "$" is required in the -lang qb dialect.
   * The string type suffix "$" is optional in the -lang fblite dialect.
   * The string type suffix "$" is ignored in the -lang fb dialect, warn 
     only with the -w suffix compile option (or -w pedantic compile 
     option).

Differences from QB
   * In QBASIC, there was no way to specify the number of digits returned.
   * The size of the string returned was limited to 32 bits, or 8 
     hexadecimal digits.
