将int转换为float到hex

试试这个:

int i = 2;
float f = (float)i;
printf("%#08X", *( (int*) &f ));

@Corey:

让我们从里到外解析它:

&  f = address of f = say address 0x5ca1ab1e
(int*)  &f = interpret the address 0x5ca1ab1e as integer pointer
*  ((int*)&f) = get the integer at address 0x5ca1ab1e

以下更简洁,但很难记住C语言的运算符关联性和运算符优先级(我更喜欢一些添加的括号和空格提供的额外清晰度):

printf("%#08X", *(int*)&f);
