Floating point does not always represent some numbers precisely
0.5 and 0.25 are simple binary fractions of 1, floating point will represent it perfectly as long as it has 2+ bits of fraction. For 32-bit floats, anything inside +/-2 million will work perfectly.
Computationally speaking, this is the most direct method: Multiply by 4, strip off decimals, divide by 4.

My script is as follows

ppi::token::quote
PPI::Token::Quote(3) User Contributed Perl Documentation PPI::Token::Quote(3)NAME
PPI::Token::Quote - String quote abstract base class
INHERITANCE
PPI::Token::Quote
isa PPI::Token
isa PPI::Element
DESCRIPTION
The "PPI::Token::Quote" class is never instantiated, and simply provides a common abstract base class for the four quote classes. In PPI,
a "quote" is limited to only the quote-like things that themselves directly represent a string. (although this includes double quotes with
interpolated elements inside them).
The subclasses of "PPI::Token::Quote" are:
'' - PPI::Token::Quote::Single
"q{}" - PPI::Token::Quote::Literal
"" - PPI::Token::Quote::Double
"qq{}" - PPI::Token::Quote::Interpolate
The names are hopefully obvious enough not to have to explain what each class is here. See their respective pages for more details.
Please note that although the here-doc does represent a literal string, it is such a nasty piece of work that in PPI it is given the honor
of its own token class (PPI::Token::HereDoc).
METHODS
string
The "string" method is provided by all four ::Quote classes. It won't get you the actual literal Perl value, but it will strip off the
wrapping of the quotes.
# The following all return foo from the ->string method
'foo'
"foo"
q{foo}
qq <foo>
literal
The "literal" method is provided by ::Quote:Literal and ::Quote::Single. This returns the value of the string as Perl sees it: without the
quote marks and with "\" and "'" resolved to "" and "'".
The "literal" method is not implemented by ::Quote::Double or ::Quote::Interpolate yet.
