How to write negative numbers in Hebrew?

[r12a]

I am lead to believe that a negative number in a Hebrew sentence should look like -23. Is this correct?

CLDR seems to suggest that the order in which the negative number is typed is hyphen, two, three.

If i do that, what i see displayed in a browser is 23-, which would be fine for Arabic, but doesn't seem to do what's needed for Hebrew.

How do Hebrew users manage this? NB: I'm more interested in how they actually do it, rather than in how they could do it in theory.

Here's a test page (Btw, it's possible to edit that test easily, take a snapshot, and provide the URL to show any changes.)
