Hi, it seems you are right: https://en.wikipedia.org/wiki/Extended_precision#Working_range

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
