.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module provides numeric data types for use with Class::Meta attributes.
Simply load it, then pass the name of one of its types to the
\&\f(CW\*(C`add_attribute()\*(C'\fR method of a Class::Meta object to create attributes of the
numeric data type. See Class::Meta::Type for more
information on using and creating data types.
.PP
The validation checks for Class::Meta::Types::Numeric are provided by the
Data::Types module. Consult its documentation to find out what it considers to
be a number and what's not.
