4b21526310 Fix test expectation (#3357) 
The test expects a specific precision value that is not met on all V8 versions anymore due to a recent consolidation of different algorithms across the V8 code base.

This makes sure the preceision is tested against one digit less to keep the test working on all V8 versions.

9aae4f2424 make tests compatible with Node.js 12 (#3304) 
In Node.js 12, the formatting of console arguments will change slightly.
Previously, a string other than the first argument was formatted using
single quotes if the first argument was non-string. Now, quotes are
never added regardless of position of a string argument.

To make test compatible in all Node.js versions, I work around by
ensuring the first argument to console.log is a string which prevents
the quotes from being added on older versions of Node.js.
