I think you need to at least provide the option, for people who want to write portable code.
Definitely. I'll try to change the operators (times,plus etc.) to use integral operations only.
It doesn't have to be all that ugly, you know. Do you need more than 32 bits after the decimal point?

Not bad. The double type does have 16 decimals precision. Is it an option to use long long for the decimal part?
Only on compilers that support it. Again, that's a non-C++98 extension.
I discovered that using base 2 exponent in stead of base 10 exponent
I don't understand what you mean her. Where is this exponent used? Does the user specify the exponent in base 2 (probably not)? YOu must mean in the representation?
gives you the same accuracy as with a regular double expression.
Is this an absolute requirement, ^^^^
a base 2 exponent or the same accuracy as a double?
or is an approximation to double sufficient?
I don't know. Better ask your target audience! I'd guess they don't want an approximation, but I'm only guessing. -- Dave Abrahams Boost Consulting www.boost-consulting.com
