NAME

GetNum - coerce scalars into numbers or return undef

SYNOPSIS

 use GetNum;

 my $i = get_int('foo'); # returns undef
 my $i = get_int('123'); # returns 123

DESCRIPTION

This module can be used to force scalar to be coerced into numeric types in a situation when the effect of int() to turn non-numerics into 0 (zero) is not desirable.

This module is handy when programming a serialization strategy for a Perl object into JSON where datatypes affect the output.
