floating-point
Non-integer number format
Floating-point describes a system for representing numbers in computing where the decimal point can move to accommodate very large or very small values.
Unlike fixed-point representation, floating-point allows the same number of digits to express vastly different magnitudes: floating-point arithmetic, floating-point precision.
The term reflects how the decimal "floats" to different positions depending on the value being stored.
