Re: Exponents: whats double etc? 18 Years Ago by Rashakil Fol Not only can you store larger numbers with doubles, the numbers are stored with more precision. Re: Exponents: whats double etc? 18 Years Ago by dwks [quote]It simply means that the storage space (number of bytes) in a double is twice the storage space of a float.[/quote] Actually, the ANI standard just states that a double must be at least as large as a float (and a long double at least as large as a double). floats and doubles could be the same size, but if one of them is going to be bigger, … Re: Coding some math with fractional exponents 15 Years Ago by javaAddict What code did you use?
