When a number consists of a whole number and a decimal fraction, only one number sign is used, and it is placed before the whole number. When numbers with decimals are joined to other numbers, the number sign is repeated following the hyphen or dash. A number containing a decimal point can never be divided between lines. Examples:

90.9 MHz | .5-1.2 | ||

6—7.25 | 7.25—8 |
