In C code you can write an integer constant in hexadecimal by prefixing
it with 0x -- so 0x32 is the hexadecimal constant equal to decimal 50.
if ( x == 0x32 ) ...
I guess that's what you're asking; '32/' is not any sort of syntax I've
ever seen before to indicate hexadecimal.
Tempted to interpret it as 32 shillings old money (£1.60 in decimal coinage)
