decimal point.



A negative exponent is the number of places to the right of the
decimal point to get to the right of 1.



To enter in your calculator,  you first enter 1
(because in scientific notation it's really 1 X 106 for example),
then enter either EE or EXP or EEX to indicate that a power of 10 is next,
then enter the number of the exponent
(and change sign if negative with the +/- or CHS key).
