Webb6 apr. 2009 · A floating point number has 64 bits that encode a number of the form ± p × 2 e. The first bit encodes the sign, 0 for positive numbers and 1 for negative numbers. The next 11 bits encode the exponent e, and the last 52 bits encode the precision p. The encoding of the exponent and precision require some explanation. WebbThe largest negative number the exponent can hold is 100. The smallest negative number that this byte can hold therefore is 1.0111 x 2 100. This is the same as -0.1001 x 2 -4 or -0.00001001, or -0.03515625. You have a fixed number of bits. You have to decide how many bits to use for the mantissa and the exponent.
