Re^3: Math::BigInt and Leading Zeros

The underlying perl library natively handles strings fine - just change '%25d' to '%25s':

  zen% perl -MMath::BigInt -e '$i = Math::BigInt->new("123_456_789_000
+_000"); printf "%025s\n", $i'
  0000000000123456789000000
  zen%

You may not have tried a big enough number. `$ perl5.8.6 -MMath::BigInt -e '$i = Math::BigInt->new("123_456_789_000 +_000_000_000"); printf "%045d\n", $i' -00000000000000000000000000000000000000000001` [download]	[reply] [d/l]

You're still trying to use decimals (%d), when the parent suggested using strings (%s): `use Math::BigInt; my $i = Math::BigInt->new('123_456_789_000_000_000_000'); printf qq'%045s\n', $i; __OUTPUT__ 000000000000000000000000123456789000000000000` [download] radiantmatrix `require General::Disclaimer; s//2fde04abe76c036c9074586c1/; while(m/(.)/g){print substr(' ,JPacehklnorstu',hex($1),1)}`	[reply] [d/l]

You're right. I completely and utterly missed that. Thanks. Oh, and thanks above - I didn't even realise that %s could take the 0 modifier. Which is probably why I missed the change from %d to %s!	[reply]
