map Examples
lmap(odd, [2, 3, 4, 5,
6, 7, 8, 9])
==> [0, 1, 0, 1, 0, 1, 0, 1]
lmap(is_prime, [2, 3, 4, 5, 6, 7, 8, 9])
==> [1, 1, 0, 1, 0, 1, 0, 0]
map(square, [2, 3, 4, 5, 6, 7, 8, 9])
==> [4, 9, 16, 25, 36, 49, 64, 81]
==> [0, 1, 0, 1, 0, 1, 0, 1]
lmap(is_prime, [2, 3, 4, 5, 6, 7, 8, 9])
==> [1, 1, 0, 1, 0, 1, 0, 0]
lsquare(X) = X*X;
map(square, [2, 3, 4, 5, 6, 7, 8, 9])
==> [4, 9, 16, 25, 36, 49, 64, 81]
In rex,
we can define functions
by equations this way.
