The sqrt() function takes a single argument (in double) and returns its square root (also in double). The sqrt() function is defined in math.h header file. To find the square root of int, float or long double data types, you can explicitly convert the type to double using cast operator.

sqrt is required by the IEEE standard to be correctly rounded from the infinitely precise result. In particular, the exact result is produced if it can be represented in the floating-point type.

The C library sqrt () function of type double accept the variable x (double) as parameter to return the result of square root. The square of a number is obtained by multiplying the number by itself.
