| Re: A missing (?) function: exponentfp(x) |
Dear Ilya,
How about something like this?
? install("exponentfp","G");
? exponentfp(2^30-1)
%2 = 29.999999998656385002
? exponentfp(Pi)
%3 = 1.6514961294723207175
? z = Pi*2^20
%4 = 3294198.6583305710348142047482656880163
? for(i=1,10^6,exponent(z))
cpu time = 276 ms, real time = 276 ms.
? for(i=1,10^6,exponentfp(z))
cpu time = 312 ms, real time = 312 ms.
Cheers,
Aurel
