It is better if you trimmed off trivial compiler specific codes. Not
everybody has the compiler that you have.

No reason to use float in this situation.
Beside, seriously consider using more meaningful identifier name.

x = a / 100;
y = b / 100;
will get the "hours" part.

i = a % 100;
j = b % 100;
will get the "minutes" part.

Your entire nested if-else block above is essentially this:
hour += minute / 60;
minute = minute % 60;
