Python中错误 overflow encountered in double_scalars 的原因 双标量具有较高和较低的范围。 较小数字的算术计算通常会产生结果,但是当这些数字的幂超过某个阈值时,就会出现 double_scalars 遇到的溢出问题。 让我们看一个例子来理解它。 该程序显示双标量的范围,在范围的边界显示计算结果,然后显示发生溢出错误的点;...

你尝试用一个int型的M作为除数，结果赋值给double型的real和imag，建议在M前加上（double）强制类型转换，即real=d_buffer[i][0]/(double)M;imag=d_buffer[i][1]/(double)M;最后的max=magnitude[0];magnitude明明是double型变量，不是数组 ...
