There is also related bug report:
http://bugs.freepascal.org/view.php?id=28737
And look at part of code in rtl/objpas/sysutils/sysstrh.inc:
41 {$if defined(FPC_HAS_TYPE_EXTENDED) or
defined(FPC_HAS_TYPE_FLOAT128)}
42 MinCurrency: Currency = -922337203685477.5807;
43 MaxCurrency: Currency = 922337203685477.5807;
44 {$else}
45 MinCurrency: Currency = -922337203685477.0000;
46 MaxCurrency: Currency = 922337203685477.0000;
47 {$endif}
Why is for case not defined(FPC_HAS_TYPE_EXTENDED), MinCurrency
defined as is ?
I think that on those targets, some currency handling is still (or
was?) implemented via the double type (instead of fixed point using
int64),
Is there way how to check current status?
If there is still need for conditional definition ?
(if I look at occurences of MinCurrency in RTL source code, I think,
that it can be adjusted ... in other words what is risk of changing
MinCurrency and MaxCurrency constants ... IMO is better if they will
have same value on all platforms, which supports Int64)
Because for example on Win64/x86_64 target, there is not defined
FPC_HAS_TYPE_EXTENDED, so I get "truncated values"
" -922337203685477.0000"
Oposed to Win32/i386, where I get
"-922337203685477.5807"
And secondly why is MinCurrency "-922337203685477.5807" and not
"-922337203685477.5808"
(see mentioned bug report)
