关于将single型的变量值copymemory到内存后的格式有关问题

关于将single型的变量值copymemory到内存后的格式问题?
将single型的变量值copymemory到内存，再一个字节一个字节读出，不知道结果的格式是什么，请教高人

'以下是single输出结果
-----------------------
Byte   1=0
Byte   2=0
Byte   3=2
Byte   4=66
-----------------------

'以下是double输出结果
Byte   1=0
Byte   2=0
Byte   3=0
Byte   4=0
Byte   5=0
Byte   6=64
Byte   7=64
Byte   8=64
-----------------------
