floating point
In computing, a formulaic representation of real numbers (whole numbers or fractions) as a sequence of digits separated by a decimal point. Depending on the number represented, the position of the decimal point moves (“floats”) left or right relative to the significant digits. Floating point numbers can represent both very large and very small numbers using a limited number of bits. Motion uses floating-point numbers (sometimes called float) to calculate values (such as color) quickly and precisely at orders of magnitude large and small.
