Summary[edit]
XREAL WORLD=Y∙2N
N可以为正或负， 2N定义了Y尾数LSB的大小。使用Linear11格式可以表示的最小数字是±2-16 x 1 = ±15.3e-6，最大数字为±33.5e6。 由于Signed（有符号）11位整数为-1,024至+1,023，尾数的大小应介于512和1,023之间。由此可以得出一种将实际值编码为PMBus Linear11格式值的方法。即N从-16开始递增，并保持尾数大小在所需范围之内。
N can be positive or negative, 2N defines the size of Y mantissa LSB. The smallest number that can be represented using the Linear11 format is ±2-16 x 1 = ±15.3e-6, and the largest number is ±33.5e6. Since Signed 11-bit integers are -1,024 to +1,023, the size of the mantissa should be between 512 and 1,023. This leads to a way to encode the actual value into a PMBus Linear11 format value. That is, N is incremented starting from -16 and keeping the mantissa size within the required range.
