::Hex2dec v2.03 - converts hex to decimal and vice versa
::Copyright (C) 2012-2013 greg zakharov

::Usage: hex2dec [decimal | hexademical]

::Example 1:
:: C:\>hex2dec 0x017a
:: 0x017A = 378
::You'll got the same result with x17a or 17a numbers.

::Example 2:
:: C:\>hex2dec 13550
:: 13550 = 0x34EE

::Example 3:
:: C:\>hex2dec 23f
:: 0x23F = 575

::Note: hex2dec starts with interactive mode if there is
