# E0030: octal literal may not have exponent

Decimal number literals can contain exponents. Octal number literals, which start with an extra `0` digit, cannot contain exponents:

    const googol = 01e+100;

To fix this error, make the number literal a decimal number literal by removing the extra leading `0`:

    const googol = 1e+100;

Introduced in quick-lint-js version 0.2.0.
