So isnan has isnan, isnanf, and isnanl.

isinf has isinf, isinff, isinfl,

finite has finite, finitef, finitel.  Note that finite is not isfinite{f|l}, so it lacks the symmetry that isinf and isnan have. Stated another way, isfinite (the type-generic macro) does not conflict with the finite, finitef, and finitel functions (like isnan and isinf do).
