(30 pts) In addition to the default IEEE double-precision format (8 byte 64 bits) to store floating-point numbers, MATLAB can also store the numbers in single-precision format (4 bytes, 32 bits). 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: Sign Signed exponent Mantissa 23 bits L bit 8 bits Determine the smallest positive value (expressed in base-10 number) that can be represented using...

IEEE 754-2008 contains a half precision that is only 16 bits wide. The leftmost bit is still the sign bit, the exponent is 5 bits wide and has a bias of 15, and the mantissa is 10 bits long. A hidden 1 is assumed. Write down the bit pattern to represent -1.6875 X 100 assuming a version of this format, which uses an excess-16 format to store the exponent. Comment on how the range and accuracy of this 16-bit floating...
