Definition: exponent

The number written above the line and to the right of a number that indicates the power of a number. For example, 14 to the 4th power is actually 14 multiplied by itself four times. Sometimes, the exponent naturally indicates the number of zeros. For example, 10 to the 3rd power reflects three zeros. The number 467,000 can be stated as 467 x 10 to the 3rd. On a screen or printout, that number is expressed as 467E3. See floating point.
