这是一个完整；BCD浮点包为8051微—
控制器。它提供了8位的指数，精度
；范围从127到127。尾数是压缩BCD码，而
；指数是伪二表达的补充。一零指数
；是用来表示数为零。指数值为80H或
；大于意味着指数为正，即80h = 0，
；81h = E + 1，82H = E + 2等。如果指数7FH或更少，
；指数为负，7FH＝1，7eh = E-2，等等。
；所有的数字都被假定为归一化和所有的结果
归一化后的计算。归一化的尾数＞＝10。
；< = 99999999。
；
；在记忆数字假定要被存储，如下：
；- This is a complete BCD floating point package for the 8051 micro-
controller. It provides 8 digits of accuracy with exponents that
range from+127 to-127. The mantissa is in packed BCD, while the
exponent is expressed in pseudo-twos complement. A ZERO exponent
is used to express the number ZERO. An exponent value of 80H or
greater than means the exponent is positive, i.e. 80H = E 0,
81H = E+1, 82H = E+2 and so on. If the exponent is 7FH or less,
the exponent is negative, 7FH = E-1, 7EH = E-2, and so on.
ALL NUMBERS ARE ASSUMED TO BE NORMALIZED and all results are
normalized after calculation. A normalized mantissa is >=.10 and
<=.99999999.
The numbers in memory assumed to be stored as follows:
