exponent

In mathematics, long, multi-digit numbers are represented in exponential notation. This simplifies the representation and the calculation considerably.

Such an exponential number representation consists of the mantissa, which is the digit

thatindicates the valence, the base and the exp

onent.

Mantissa, base and exponent of a number

The exponent (exp) is the superscript by which the base is exponentiated. This is positive when dealing with values greater than 1, and negative when dealing with values less than 1. For example, the number 1 000 000 in exponential notation with base 10 becomes 10exp6, or the number 0.000 004 567 becomes 4.567exp-6. In these examples, the exponent is +6 and -6.
