E0031: octal literal may not have decimal

Decimal number literals can contain a decimal (fraction). Octal number literals, which start with an extra 0 digit, cannot contain a decimal:

const PI = 03.14;

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

const PI = 3.14;
