I was doing some proofreading and ran across the word "calculate-able." I'm tempted to write this out as the question suggests ("able to be calculated") but was wondering if there was a more terse alternative.

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information.If this question can be reworded to fit the rules in the help center, please edit the question.

This is readily searchable so it should probably be closed as General Reference, but in the meantime, the word "calculable" is a more succinct version. –  Kristina Lopez Apr 17 '13 at 17:20

Calculable is a real word.

  1. determinable by calculation; ascertainable: This map was designed so that distances by road are easily calculable.

  2. that can be counted on; reliable.

Thanks, I was worried about the other definitions, along the lines of "predictable". But this seems as straightforward as possible. –  user Apr 17 '13 at 16:31
@DinH: The other senses should be regarded largely as independent (though of course not totally unconnected) - the compilers don't mean that the 'one true meaning' of a word lies somewhere in between the 2, 3, or 47 senses ('polysemes') given for that particular word. Also, the first sense listed is often the one most commonly used. –  Edwin Ashworth Apr 17 '13 at 18:27

As mentioned in another answer, calculable is a word that can be used here. It means “Able to be calculated”.

An alternative: computable, with senses “Capable of being computed” and “(computing theory) algorithmically computable, i.e. able to be calculated by a Turing machine”. If the Church-Turing thesis holds (as it does for everything studied so far), then the set of effectively calculable functions coincides with the set of algorithmically computable functions, making computable a suitable alternative to calculable.

+1 for mentioning "computable", a choice I would prefer. –  KeyBrd Basher Apr 18 '13 at 5:18
