The "0x" is taken from the C programming language; it indicates that the number in question is hexadecimal.  One must 
take note of it as an indication that what follows it is hexadecimal; neither the 0 nor the x are digits that directly 
contribute to the number's value.

It's a 4-digit hexadecimal number, whose value is hex c13e, or decimal 49470.

c13e; it's a single two-byte big-endian value, the two bytes of which are hex C1 and hex 1E.
