推荐答案

这是我之前编写的函数.当它存储在内存中时，它以1英寸和0英寸打印一个float变量(它以IEEE单精度浮点数标准存储).

Here is a function that I have written before. It prints a float variable in 1''s and 0''s as it is stored in the memory (it is stored with the IEEE single precision floating point numbers standard).

void printFloat(float a)
{
	unsigned long* temp = (unsigned long*)&a;
	unsigned long one = 1;

	for(int  i = 31; i >= 0; i--)
	{
		if(((*temp) & (one << i)) == 0)
			cout << "0";
		else cout << "1";

		if (i % 4 == 0)
			cout << " ";
	}

	cout << endl;
}

我不确定这是否是您所需要的.希望对您有所帮助.

I''m not sure if this is what you need. Hope it helps.
