## Definitions

### Computing

### Electronics

- A numeric
__format__ in which each number is represented by two numbers, and in which the __decimal point__ is not in a fixed location. The first number, the __mantissa__, specifies the significant digits, while the __second__ number, or __exponent__, specifies its magnitude. For example, 314,000,000 may be expressed as 3.14 × 10^{8}. Although any number, with any radix, may be represented in this manner, it is usually used only for very small or very large numbers. Also called floating-__point__ representation, __scientific notation__, or __exponential notation__. When an __E__ is used instead of a 10, or the radix utilized, it is also called __E notation__. - synonymfloating-point representation
