Floating point error problem in programming

So i moved on to programming. I compiled the program using while loop and break conditions. After completing and running the program i got error message showing "encountered a floating point error".Dont know how to fix the bug.. Can anyone help me pls?????????

Somewhere within your loop the deltaP .dc and .r variables are blowing up to the limits of numeric handling (ie, they're in the order of 10^{307 )}
