Number’s decimal places lost in email notification

I have a form with a currency field and a number field both configured for 2DP. I submit the form with 12.34 in both fields When I send an email notification containing these fields: The currency field (correctly) displays the decimal places, but the number field doesn’t – it just displays an integer (e.g. 12).

When I went to check that the form submission had saved the correct values, the summary line shows the decimal places for both fields. If I click to see full details, both values show without their decimal places (e.g. 12).
