For Part A, you must do the calculations by hand, but you may want to verify if your solution is correct using MATLAB's format hex command. Convert 0.625 into a single-precision IEEE 754 floating-point number and express the results in hex form. Convert 0.625 into a double-precision IEEE 754 floating-point number and express the results in hex form. Convert -1.0 into a single-precision IEEE 754 floating-point number and express the results in hex form. Obtain the hex digits for the 32-bit, 2s complement integer for -1. You do not have to work out this conversion by hand, you can use MATLAB's int32 function and format hex command. Why are the hex digits of (a) and (b) different? Convert the IEEE 754 floating point number BD800000 into a decimal number
