For data where greater precision is required, we must use two or more bytes. For example, two hexadecimal numbers aa bbH expressing two 7-bit bytes would indicate a value of aa x 128 + bb. In the case of values which have a +/-sign, 00H = -64, 40H = +/-0, and 7FH = +63, so that the decimal expression would be 64 less than the value given in the above chart. In the case of two types, 00 00H = -8192, 40 00H = +/-0, and 7F 7FH = +8191. For example if aa bbH were expressed as decimal, this would be aa bbH - 40 00H = aa x 128 + bb - 64 x 128. <Example 1> What is the decimal expression of 5AH?>From the preceding table, 5AH = 90 <Example 2> What is the decimal expression of the value 12 34H given as hexadecimal for each 7 bits?
