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.
