Add support to match integers and floats

[LindomarReitz]

The main idea here is to able to match integer/float values, not only strings.

It helps to validate more fields in the pact expectations, if necessary.

Hi,

Thanks for adding this, however, as pact is a multi-language implementation, we need to add changes like this to the pact specification, and add the equivalent functionality to the JVM/rust implementations as well.

@uglyog what do you think about using regular expressions on strings?

[uglyog]

@bethesque regular expressions on strings will never work ;-)

I think you mean regular expressions on numbers? I'm happy to apply regular expressions to anything, converting them to strings for the comparison.

[bethesque]

Yes. :%s/strings/numbers/.

Ok. @LindomarReitz how do you feel about adding some test cases to the latest pact-specification?

Thanks for this @LindomarReitz

Just picking up this thread, I believe this is done (in the pact-specification), looking at the above merge, and closes an outstanding issue in specification, details linked in

pact-foundation/pact-specification#39

are we there in terms of language support, I noted this was added to the v2 spec but the link in beths comment takes me to the v4 spec

closing in favour of #108

Thanks for your contribution
