Is scientific notation safe for integer constants in C?

Question

For a while, I\'ve been representing large powers of 10 in constants using scientific notation, just so I don\'t have to count the zeros. e.g.

#define DELAY_USE         


        

Answer 1

You'll never get rounding errors on something less than INT_MAX, since the specification for double sets aside 52 bits for you to use. Your "fractional component" is just your integer, and your "exponent" will be 1, and floating point doesn't struggle with that.
