Some programming languages treat the results of comparative primitives such as = as True and False values that are not numbers. In J the results of comparatives are just numbers.
There are several other comparative verbs: less-than < , less-or-equal <: , larger-than> , and larger-or-equal >: . These comparative primitives are sometimes called relationals.
