I have a calculator program, beyond certain size numbers it resorts to real
numbers, when sometimes I want exact integers.
eg 17! (17Factorial) is the highest I can get exactly (17*16*15 etc.), 18!
turns to a real number and I don't know if I am losing digits.
Another example of large numbers is time converted to milliseconds:
Thisint64:=strtoint(formatDateTime('yyyymmddhhnnsszzz',now)); (I
don't do arithmetic on that but it is 17 digits)
My main guess about int128 is that if it were there it could give real
numbers to a higher number of precision digits (only 15-16 with current
real).
would be cool to store numbers like
pi=3.141592653589793238462643383279502884197169399375105820974944 if my
memory serves me correctly. Delphi cannot provide such accuracy.
Reason I asked is I heard that after Windows 7 one of the supposed versions
of Windows being considered was a 128 bit version. Also 64bit Delphi on the
horizon suggests that larger integers might be coming.
