How to type a decimal point
Continuing my occasional series of typographic typing tips (I like that alliteration). Usually we use the full stop as the decimal point in a number but strictly speaking the decimal point should be at middle height of the digits not at the base. You want 123·45 and not 123.45 What you need to type is called an interpunct or dot space. The way to do this on a Windows computer is a bit awkward.
