Module Version: 0.40
HTML::Fraction - Encode fractions as HTML entities

my $fraction = HTML::Fraction->new; print $fraction->tweak($html);

The HTML::Fraction encodes fractions as HTML entities. Some very common fractions have HTML entities (eg 1/2 is ½). Additionally, common vulgar fractions have Unicode characters (eg 1/5 is ⅕). This module takes a string and encodes fractions as entities: this means that it will look pretty in the browser.

Fractions that are supported: 1/4, 1/2, 3/4, 1/3, 2/3, 1/5, 2/5, 3/5, 4/5, 1/6, 5/6, 1/8, 3/8, 5/8 and 7/8.

Fractions may be in the string in the form numerator slash denominator ("1/5") or in decimal form ("0.5"). Numbers that do not have exact decimal representation must be equal to the fraction to two decimal places. This module supports converting whole and fractional decimal numbers (e.g. "2.25".)

The constructor takes no arguments:

my $fraction = HTML::Fraction->new;

Encode the fractions in the HTML as HTML entities:

print $fraction->tweak($html);

Encode the fractions that are in the form "1/3" or "5/6" in the HTML as HTML entities, but not decimal fractions of the form "0.5".

Encode the fractions that are in the form "0.5" or "0.5" in the HTML as HTML entities, but not fractions of the form "1/2" or "1/3".

We don't perform normalisation of the denominator and numerator so "4/6" is not converted like "2/3" is. This is intentional

2.25 doesn't render to the same thing as 2 1/2 (the latter has a space between the digit 2 and the fraction.)
