[julia-users] generating hex from string

[Martin Somers]

I seem to be getting an error of an ill formed hex number 
ERROR: LoadError: ArgumentError: string length must be even: 
length("ac446e2") == 7

Im using 
parse(("0x"*bytes2hex(y))

is there a better way maybe of doing this one of my y indexs isnt in fact a 
UInt8 values

Im initialising y = [0x00,0x00,0x00,0x00];
