I suspect that real[3] is really 5.99999999999999...
"%f" format rounds to 6 decimal places by default.
When you use %d format it simply truncates it down to
an integer rather than rounding it.

Use "%.0f" (that's point *zero*) instead of "%d".
You'll get the value displayed as an integer with
no decimal places and no decimal point. i.e. you'll
see: 6
