Function

Number ( func pred ) -> func ctr

Description

Construct a functional `ctr(<list> l) -> elt-ord^rat' which returns the number of elements from `l' which suffice the predicate function `pred'.
Note: Apparently `pred' must have `-> elt-alg^boo' out-signature.

Examples

f:=Number(IsPrime); f([1..100]);
