Maybe this is a bug but I am unsure...

I changed bigmath.exw to

d1 = "12345678901234567895555555555555555555555555555555555555"
d2 = "23"

Then I got

12345678901234567895555555555555555555555555555555555555 * 23 =

time: 0.17

12345678901234567895555555555555555555555555555555555555 / 23 =

12345678901234567895555555555555555555555555555555555555 mod 23 =
12345678901234466732222570260054862476056751058910461131

Why is the last test can be larger than 23?

Thanks for the library.
