Sqrt C Math
To use it include the math h header file in the program.
Sqrt c math. The sqrt function takes a single argument in double and returns its square root also in double. The c library function double sqrt double x returns the square root of x. 4 a set of overloads or a function template accepting an argument of any integral type. 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 exact. In other words the error is less than 0 5 ulp. This function is overloaded in complex and valarray see complex sqrt and valarray sqrt. 1 3 computes the square root of arg.
Square root in c using sqrt function. The only other operations required to be exact are the arithmetic operators and the function fma. The sqrt function computes the non negative square root of x i e sqrt x for complex numbers x sqrt returns the complex root of x using the following formula 2 where is the argument of x. Function sqrt in c returns the square root of a number.
Mathematics x sqrt x in c programming the sqrt function is defined in math h header file. Header tgmath h provides a type generic macro version of this function.
