Need negative decimal number values in Product features

Because diopters of glasses can be negative and decimal.

I can’t figure out how to change this. Looks like need changes in /skins/[SKIN_NAME]/admin/views/product_features/manage.tpl and update.tpl to replace cm-value-integer. Simply removing this doesn’t work properly, as allows to input any text in this case.

Please help!

I know this is an old thread, but I've gone through these boards for hours searching for something similar.

I simply wish to be able to add features that are specified as a number with two decimal places. I'd have no problem just using the “text” type, but this won't let me filter the options later on. When I try to enter decimals as a “number” type, the decimal point vanishes as I type, presumably because it isn't allowed.

Does anyone have any suggestions?
