it's that "64 bits of mantissa" which will bite your ass in the end. of what use is an exponent of 4932 when there are lots of zeroes there?

ditto my argument. if you have such a great "need" for BIG NUMBERS, and you don't like approximating or just plain GUESSWORK (which is what all those zeroes mean..) GMP or PARI ought to be the way to go..

AFAIK, on an x86 machine, a long double would be the ten-byte, 80-bit
representation of floating point numbers that every x86 FPU since the

bit mantissa, allowing one to represent numbers up to 10^4932 with up to
19 significant decimal digits.
