I’ve Floating-Point Arithmetic in Matlab Since real numbers can not be coded with flnite number of bits, Matlab and most other technical computing environments use °oating-point arithmetic, which involves a flnite set of numbers with flnite precision. The number 0. Of course, while the above is very succinct from the user standpoint and an extremely handy facility, it doesn't actually change the underlying fact that the value '21' is still stored as twos-complement integer whether BASE is set at 2 or 10 or 16 or 37 (a value handy to use for encoding simple hash table keys or the like); the same cast operations between Decimal floating to binary. However for binary the same value could be 1. To try the progra Represent Array of Floating-Point Numbers. For example, >> b = 0.
