This is a common error while compiling C program in GCC/G++ Linux. This error occurs when you are using sqrt function to find square root of a number in your programs.To fix this problem ensure following pointsInclude header file math.h in your program. Add –lm linker flag with ...
你把你的整型变量或者表达式乘以1.0，然后作为sqrt的参数，这样就可以了。你没有sqrt的源程序，是无法对sqrt进行调试的。

In this example, the program prompts the user to enter a number (5). The Exponential Function Method is then applied to calculate the square root, resulting in a precision of approximately 2.23607.Note that the method relies on the <cmath> library for mathematical functions, so ensure proper...

Because C++ allows overloading, you can call overloads ofsqrtthat takefloatorlong doubletypes. In a C program, unless you're using the<tgmath.h>macro to call this function,sqrtalways takes and returnsdouble. If you use the<tgmath.h> sqrt()macro, the type of the argument determines whic...
Hello: In computing the sqrt of a complex number I found that under certain conditions (with or without -O0) a program may return the positive of the
