Ford Windstar Owner's Manual page 81

Some FM radio stations advertise a "rounded-off" frequency
which is not the frequency they actually broadcast on. For
example, a radio station that is assigned a frequency of 98.7
MHz may call itself "Radio 99" even though 99.0 MHz is not an
allowable FM broadcast frequency.
