## E0044: unexpected characters in number literal

Letters are allowed in number literals in certain situations, such as in `123n`, `1e6`, and `0xff`. It is an error to include other letters or letters in the wrong spot:

    let gazillion = 10000000000000000000000000N;
    let pi = 3.14l;
    let tau = 2pi;

To fix this error, use the correct letter or remove the extraneous letter:

    let gazillion = 10000000000000000000000000n;
    let pi = 3.14;

Alternatively, use the `*` operator to multiply a variable by a number:

    let tau = 2*pi;
