== "Interpret linepos as a (potentially signed) rea..." ==
http://w3c.github.io/webvtt/#cue-timings-and-settings-parsing

> Interpret linepos as a \(potentially signed\) real number, and let 
number be that number\.

Unclear what this means for `-0` or if the output can be 
Infinity/-Infinity.

I think we should use 
https://html.spec.whatwg.org/multipage/infrastructure.html#rules-for-parsing-floating-point-number-values
 which parses `-0` into +0 and avoids infinities.
