19.99 or 3.5. Use this to confirm that a field like a price, weight, or rate really holds a fractional number before you calculate with it. This is the strictest of the number checks: only a genuine decimal number matches. A whole number such as 42 is treated as an integer, not a float, so it does not match, and text such as "19.99" does not match either because it is text rather than a number. This condition has no settings: it looks at whatever value it is given and reports whether that value is a decimal number.
