Floating point is a numeric system for approximating real numbers. Each floating-point number stores some digits and an exponent, taking the form
- value = digits × RADIXexponent
This design uses a constant RADIX and limits the maximum number of digits. Calculations are fast but inexact, because the limit on digits causes round-off errors.
