Re: More floating point digits?

[Daniel Diaz]

In gprolog, a float is represented as a C double which is represented on 64 bits independently from the underlying architecture (32/64 bits machines).
There is no way to increase this precision.

I checked a 64-bit and 32-bit system for max_integer with the following results:

AMD Athlon 64 max_integer is 1152921504606846975 :)

Intel Pentium 3 max_integer is 268435455

 

However when I check the floating point representation I always get the same

16 meaningfull digits.  The maximum exponent was 307.

AMD Athlon 64: X is (1/3).  X = 0.33333333333333331 ;)

Intel Pentium 3: X is (1/3).  X = 0.33333333333333331

 

Is there a build option when increases the floating point precision or is this

representation part of gprolog 1.3.0.
