GraphViz does not output quotes around integers, but does output quotes around floats:

$ nop <<<'graph g { x=2 }'
graph g {
graph [x=2];
}

$ nop <<<'graph g { x=2.5 }'
graph g {
graph [x="2.5"];
}

I'd prefer that it format all numbers similarly and not output quotes around floats. Could this minor discrepancy be resolved?

Thanks,
