Bug#326112: Double precision error.

Package: rpncalc
Version: 1.36.8
Severity: normal

Just discovered '33!' was off, then found this report.  A few added
details, more for BTS reading users...

All values of 'n!' over 23 are incorrect, but approximate, for example:

    source	n	result
    calc	25	1551 1210 0433 3098 5984 000000
    rpncalc	25	1551 1210 0433 3098 6055 303168

'rpncalc' is good to 16 places.

A presumably accurate table to check against:

    N. J. A. Sloane, The first 100 factorials: 
    Table of n, n! for n = 0..100 

This bug is five years old.  If a proper fix can't be had, couldn't
'23!' or greater return '+infinity'; or caution users that the
incorrect results are approximate?
