尝试一下:):

Try it :) :

#ifdef _ARM_
  bARM = TRUE;
#endif // ifdef _ARM_
...
}

您是否听说过

鉴于您所指出的定义，浮点数"自恋数字正好为零.所有已知的88个以10为底的自恋数字都是整数.

看看这个概念背后的数学原理，这很容易测试.但是，由于Long Integers的限制，您将需要一个BigInteger库来处理最大的肯定标识案例.

Given the definition you pointed out, there are precisely zero "floating point" narcissistic numbers. All of the known 88 base 10 narcissistic numbers are integers.

Looking at the math behind this concept, this is ridiculously easy to test for. Though, due to the limitations of Long Integers, you''ll need a BigInteger library to handle the largest cases of a positive identification.
