In programming, a floating-point is a variable type that is used to store floating-point number values. A floating-point number is one where the position of the decimal point can "float" rather than being in a fixed position within a number. Examples of floating-point numbers are 1.23, 87.425, and 9039454.2. Different programming languages or systems may have different size limits or ways of defining floating-point numbers. Consult the language documentation for details.
