Re: [Dev-C++] numerical error in a simple program

[<ten...@ne...>]

The binary representation for floating point numbers cannot be perfectly 
accurate, so that imprecissions. With double variables you get better 
precission that simple float.
But if you want more precission, then, as said by w.y., there shall be 
special libraries.
