However I am unsure of how to find the mantissa/exponent. My initial idea was to convert 10^200 to 2^x. However x is not a whole number. So I figure we need to get a fraction somehow by separating the 10^200 somehow. Theoretically one could use very long devision, but I am looking for a more elegant answer that can be done without a high precision calculator. c++ floating-point binary double ieee-754 share | improve this question asked Nov 11 at 1:12 Philip Bal ...
