C Programming/math.h/sqrt

sqrt is a C library function. It is mainly associated with programming language. It is considerd under [math.h] header file. function: #include     double sqrt (double x ); float sqrt (float x ); long double sqrt (long double x );

Description: sqrt computes square root. And returns The square root of x. In C++, this function is overloaded in and (see complex sqrt and valarray sqrt). If the argument is negative, a domain error occurs, setting the global variable errno to the value EDOM.

Return Value: Square root of x.

Portability: In C, only the double version of this function exists with this name.

Example:

Output: sqrt(1024.000000) = 32.000000
