WebOften it is defined as the difference between 1 and the next greater number that can be represented exactly, sometimes it is half of this difference (as it is the maximal relative error). In general, if you look at a machine number with base b, mantissa m (and exponent e ), you can define e p s := b 1 − m 2. WebAlthough it is not commonly used, MATLAB allows numbers to be expressed in single precision. Each value is stored in 4 bytes with 1 bit for the sign, 23 bits for the mantissa, and 8 bits for the signed exponent.
