Most digital thermometers are accurate within 2/10ths of a degree.  This means a 98.6º F reading is still considered accurate, although the temperature may actually be 98.4º F or 98.8º F.  A Basal Digital Thermometer is accurate within 1/10th of a degree to better interpret event he slightest fluctuation in temperature.  Readings are displayed to a 100th of a degree (98.65ºF) for added accuracy and assurance.
