Hmmmmmmmmmmmmmmmmmmmm...

I think Veltro's point is likely irrelevant if both the Windows perl and Linux perl report the same value for $Config{nvsize}.
But if the nvsize differs between the 2 perls, then it's a different matter. For example: 
On perl-5.30.0 whose nvsize is 8 (and whose nvtype is 'double':
C:\>perl -V:nvsize
nvsize='8';

C:\>perl -le "print int(1000 * 0.001);"
1

On perl-5.30.0 whose nvsize is 12 or 16 (and whose nvtype is 'long dou
+ble'):
C:\>perl -V:nvsize
nvsize='16';

C:\>perl -le "print int(1000 * 0.001);"
0

Does perl -V:nvsize report the same value on both machines ?
Does perl -V:nvtype report the same type on both machines ?

Update: It's probably worth mentioning that both of those perls are correct in what they're doing.
The double that most closely represents the value 0.001 is actually slightly greater than 0.001
The long double that most closely represents the value 0.001 is actually slightly less than 0.001.
