求指导，1,0.5,1.5的二进制是怎么换算得出的。。完全看不明白。。
4-byte real:
SEEEEEEE MMMMMMMM MMMMMMMM MMMMMMMM
8-byte real:
SEEEEEEE MMMMMMMM MMMMMMMM MMMMMMMM
MMMMMMMM MMMMMMMM MMMMMMMM MMMMMMMM
Examples of 4-byte real:
Note: In the first six lines of the following example, the 7-bit
exponent field = 65. The actual exponent is 65-64=1.
