Ip i float rand & 0xff / 10.0f

note that if you do float f = (float)rand(); it will convert the integer into a float (thus 10 will become 10.0). So now if you want to limit the maximum value you can do something like (not sure if this works) int tmp = rand(); float f = *((float*)&tmp); tmp = (unsigned int)f // note float to int conversion! tmp %= max_number; f -= tmp; WebJun 15, 2024 · 其中有两个位运算，一个是>>，一个是&。 0xff的作用一: 十六进制0xff的长度是一个字节，即八位，二进制为：1111 1111，那么一个 8bit 数与1111 1111与运算还是这个数本身， 但是一个16bit 数与 0xff就被截断了，比如 1100110011001100 & 0xff结果为 11001100 。 那如果想不被截断怎么办？ 把0xff扩展为二个字节即：0xffff，那么以此类 …
