+1 to merge |

@bcongdon It would be good to write a test for this case as well |
|

Looks good. Thanks @bcongdon The CI error looks like its from Coveralls again, so not to worry about it :) |

FWIW, we would have to test -Infinity as well.
I would use the isFinite global function [1] (/!\ not the Number.isFinite function, which IE doesn't support [2]). The check would need to be after the "object" checks, though.

@MatthieuRivaud: Switched the logic to use isFinite() |
|
@simonbrunel @zachpanz88 can we merge this? |

Looks good to me, merge conflicts should get fixed first |

Doesn't isFinite include !isNaN?
According MDN:
Returns false if the argument is positive or negative Infinity or NaN; otherwise, true.
So could be simply if (typeof(rawValue) === 'number' && !isFinite(rawValue)) {, right?
