Re^2: frac12 to decimal

Hi Thanks - I guess that answers the question on changing the behaviour of the module without changing the module, but having said that this particular code did not bring about the desired behaviour. That's still the piece I can't figure out what's happening? The hash in the module:

%entity2char
[download]

Contains the following key value pairs that seem to govern this behaviour.


 frac14 => chr(188),
 frac12 => chr(189),
 frac34 => chr(190),
[download]

Presumably chr(188) and its brethren are taken straight from the HTML, then fracNN to which it is mapped is somehow translated to display as the tiny one character wide fraction symbol. But stating:

# switch package
package HTML::Entities;
$entity2char{frac14} = '.25';
$entity2char{frac12} = '.5';
$entity2char{frac34} = '.75';

# switch back to your package
package main;
# go on with your code
[download]

Does not seem to change that behaviour?

from HTML/Entity.pm: `# Make the opposite mapping while (my($entity, $char) = each(%entity2char)) { $entity =~ s/;\z//; $char2entity{$char} = "&$entity;"; }` [download] so try: change `%char2entity` as well `package HTML::Entities; $char2entity{'.25'} = '¼'; $char2entity{'.5'} = '½'; $char2entity{'.75'} = '¾'; package main; ...` [download] or post some code to look at.

`½` is a HTML entity, it maps directly to `chr(188)`/U+00BC, which in ISO88591 is vulgar fraction one quarter , and all computer programs which know how to display ISO88591 will draw on the screen ½	[reply] [d/l] [select]
