NAME
Data::Vitals::Util - Utility methods for the Perl "Vital Statistics" Library
DESCRIPTION
Data::Vitals::Util defines a set of functions that are used in various places within the Data::Vitals classes.
All functions are importable using the standard Exporter mechanism
use Data::Vitals::Util 'cm2inch';
FUNCTIONS
cm2inch $cm
The cm2inch
function is a specialised method for converting a centimetre measurement to inchs. It converts using the standard 2.54004 multiplier, but rounds down to the half-inch.
The algorithm used is specifically designed so that, when used as a pair with the inch2cm method, any value that cm2inch(inch2cm($x)) == $x
is always true, although it may not be true of the reverse.
It takes as argument a number without any 'cm' indicator, and returns the number of inches as a similar plain number.
