Support Infinity as precision

[Richienb]

Specifying an infinite precision will assume infinite decimal places.

roundTo(0.1231782638, Infinity);
//=> 0.1231782638

You also need to update https://github.com/sindresorhus/round-to/blob/master/index.d.ts

@sindresorhus We shouldn't have to update any types since typeof Infinity === "number".

[sindresorhus]

The docs in the TS file.

[Richienb]

Infinity is a type of number. microsoft/TypeScript#32277

[sindresorhus]

Please read my comment again. I'm talking about the docs not the types. The readme and TS file should be in sync documentation-wise.

@sindresorhus Oh right. 🤦‍♂
