in reply to built in function for binary division

Google is your friend. The substantive portion is lifted nearly verbatim from onperl.net's binary arithmetic tut. NB You'll have work to do to extend this beyond 0b111.

C:\>perl -E "my $result = 0b01011/0b11; say $result;" 3.66666666666667 # output in decimal.

for binary output:

#! /usr/bin/perl use 5.014; my @CONVERSIONS = qw(000 001 010 011 100 101 110 111); sub conv2bin{ my $octal = sprintf ("%o", $_[0]); my @threeBitSeqs = map {$CONVERSIONS [$_]} (split //, $octal); return (join "", @threeBitSeqs); } my $result = 0b01011/0b11; say "decimal: $result"; my $bin= conv2bin($result); say "binary: $bin"; =head D:\>perl bin_div.pl decimal: 3.66666666666667 binary: 011 # 3 decimal (or 3.66667 truncated) expressed as binar +y. # Now, try this dividing -- oh, say, 6dec by 2dec... =cut
