      Likewise, the 80x86 works with fixed length values, even when processing unsigned binary numbers. Zero extension lets you convert small unsigned values to larger unsigned values. To sign extend a value from some number of bits to a greater number of bits is easy, just copy the sign bit into all the additional bits in the new format.

      Unsigned binary. Integers are represented using ‘ordinary’ (unsigned) binary. Unsigned binary offers a fast and compact representation. Sample Unsigned Byte. Bit Number 7 6 5 4 3 2 1 0 Weight 27=128 26=64 25=32 24=16 23=8 22=4 21=2 20=1 Bits 1 0 1 1 0 1 1 0 The weight of a binary digit is 2 (the bit number). Handy.

      Internally, as you know, the number can be represented in binary. Write a program that 'reads' a NUL-terminated character string that represents a decimal number and produces an unsigned binary word representation of the magnitude of that number. For example, if the number is 124, the sequence of characters will be '1','2','4',NUL.

      In unsigned binary, every binary digit or bit represents a different power of two. Let’s use an example to convert a binary value back to decimal. The 8-bit unsigned binary value 00101010 has ones in the positions assigned to 25 = 32, 23 = 8, and 21 = 2. If we add these decimal values together, we get 32 + …
