fast data on LCD.
 

fast float routine in c

If your data is integer, why are you converting it to float? Simply convert the integer directly to a (decimal or hex or octal or ???) string.
 

Re: fast float routine in c

Another possible issue is that LCD modules are slow by themselves. The Enable Cycle Time for HD44780-based LCDs are already 1ms. Added to some execution time from your microcontroller and you may easily miss your deadline.
