Adding a parse method about d3-format

[existe-deja]

I agree. I'm facing this problem: I want to tween text during the update of my data. The text is in a localized percentage format.

I'm following this pattern https://bl.ocks.org/mbostock/7004f92cac972edef365. For now I got the choice between always tween from 0 to my target value, or try to parse with some RegExps the self.text() result.

It would be simpler and safer to have a parse method instead of a string.replace.

I have a doubt on new formatting style in version 4.
console.log(d3.format(",.1f")(-0.03233401761776867))
when I am consoling this in version 3 Output : -0.0
But in version 4 it is coming as 0.0
How to fix this issue ??

@jainswapnil90 Please don’t reply to unrelated issues with help requests. Use Stack Overflow to ask for help. The behavior you describe is documented in the release notes for 1.0 and 0.0 is the expected behavior in 4.0.

Closing to inactivity. I have no immediate plans to implement parsers for localized number formats (and I think that would be a lot of work!).
