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.

EXPORTED SUBROUTINES
    All subroutines are exported by default.
