Integers

In Lem, all numbers are treated as floating-point. For example, the number 2:

let two = 2;

The println built-in can print strings, integers, arrays, and booleans. It can also concatenate mismatching types, but it will not pretty-print arrays.

println("Look, a number: " + 6);

As demonstrated on the strings page, concatenating mismatching types outside of the println built-in will cause an error (see println & print for more information).
