ahah!!
using -118.4 better than 118.4 also gives me the expected result. (2287.26)
all confusion came that i i was using the wrong set of value...

Merci Cyrille,
in the formula the intermediate steps are quite small fractions and it
seems their precision is important.
In the test case the Pd implementation is 8917.74 km off the proper
result (2887.26). However I need a precision of about 1m.
So I assume the haversine formula is not implementable in Pd at all?
(unless double precision will be there that is)
I had a go at immplementing it in Pd Vanilla, with a few [expr], and the result
seems the one expected... no?
