For example, the following declarations declare variables of the same type:The default value of each floating-point type is zero, 0. The extra bits increase not only the precision but also the range of magnitudes that can be represented. The mantissa is usually a value between 0 and 1. This, and the bit sequence, allows floating-point numbers to be compared and sorted correctly even when interpreting them as integers. The number of sums that a computer can handle is measured by 'flops' (floating-point operations per second). It is a dedicated logic unit specifically designed to work on floating point numbers and nothing else, hence the name. In computing, floating point describes a method of representing an approximation of a real number in a way that can support a wide range of values.
