Hi,

I was playing a bit with floating point types when I noticed this discrepancy:

>From math.pp

{$ifdef FPC_HAS_TYPE_EXTENDED}
    const
      MinExtended  =  3.4e-4932;
      MaxExtended  =  1.1e+4932;
{$endif FPC_HAS_TYPE_EXTENDED}

>From fpc reference guide:
Extended 1.9E-4932 .. 1.1E4932

3.64519953188247460253E-4951 seems to be the lowest value I can get
while testing (Win 32 bit).

What's up with that?

Bart
