Can I use decimal in font size?

The minimum font size available in Microsoft Excel is 1 point and the maximum size is 409 points. Thus the font size may range anywhere from 1 to 409 points. As regards decimal, you can use font sizes in multiples of 0.5(e.g)1.5,2.5,3.5 etc., You can only use one decimal point and if you use more than one decimal points its rounded off. Same is the case for other decimal values. Thus if you enter 12.3 then font size is rounded to 12.5 and when you enter 12.73 then it is rounded as 13.
It should be noted that the font values should be directly entered into the font size box and cannot be selected from the dropdown box since the dropdown box contains only standard font sizes.
