# Math::NoCarry 1.10

Date Added: July 01, 2010  |  Visits: 634

Math::NoCarry is a Perl extension for no carry arithmetic. SYNOPSIS use Math::NoCarry; my \$sum = Math::NoCarry::add( 123, 456 ); my \$difference = Math::NoCarry::subtract( 123, 456 ); my \$product = Math::NoCarry::multiply( 123, 456 ); No carry arithmetic doesnt 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 cant do that, so the sum of 8 and 4 is just 2. In effect, this is addition modulo 10 in each column. I discard all of the carry digits in this example: 1234 + 5678 ------ 6802 For multiplication, the result of pair-wise multiplication of digits is the modulo 10 value of their normal, everyday multiplication. 123 x 456 ----- 8 6 x 3 2 6 x 2 6 6 x 1 5 5 x 3 0 5 x 2 5 5 x 1 2 4 x 3 8 4 x 2 + 4 4 x 1 ------- 43878 Since multiplication and subtraction are actually types of additions, you can multiply and subtract like this as well. No carry arithmetic is both associative and commutative..
