libmath-nocarry-perl - 1.117-1 main

The perl module Math::NoCarry implememnts no carry arithmetic which
doesn't allow you to carry digits to the next column. For example,
if you add 8 and 4, you normally expect the answer to be 12, but that
1 digit is a carry. In no carry arithmetic you can't do that, so the
sum of 8 and 4 is just 2. In effect, this is addition modulo 10 in
each column. The following example discards all of the carry digits:
.
1234
+ 5678
------
6802
.
For multiplication, the result of pair-wise multiplication
of digits is the modulo 10 value of their normal, everyday
multiplication.
