What does 3.500USD mean? Are we bringing back the half-penny?

[_2d30]

He’s European and uses a “.” instead of a “,”

[4gotunameagain]

Varies by country in Europe.

[a3w]

Varies by country on earth [citation needed].

You’re also not correct even if it were a decimal marker. Three dollars and fifty cents requires no half cent.

Specifying the second 0 implies portions of one cent. Like if I said something costs 10USD, the one dollar bill is implied to exist even if it isn't used (same with 10.00 implying the existence of a penny)
