The log function in C computes the base-e (natural) logarithm of x . A domain error occurs if the argument is negative. A pole error may occur if the argument is zero. The x is the argument that is passed into the log(). It is declared in math.h and takes one argument in the form of double and
The fabs function in C computes the absolute value of a floating-point number x. The x is the argument that is passed into the fabs(). It is declared in math.h and takes one argument in the form of double and returns the value of type double. Example, Input : 3.5 Output : 3.5 Input : -2.6 Output :

The floor function in C computes the largest integer value not greater than x. In other words, you can say that the floor function computes the largest integer value not greater than x. The x is the argument that is passed into the floor(). It is declared in math.h and takes one argument in the form of double

The pow function in C computes x raised to the power y (xy). A domain error occurs if x is finite and negative and y is finite and not an integer value. A domain error may occur if x is zero and y is zero. A range error occurs if the magnitude of nonzero finite
The sqrt function in C computes the nonnegative square root of a given number (sqrt parameters). It is declared in math.h and takes one argument in the form of double and returns the value of type double. You should remember that if the argument is less than zero, a domain error occurs. Syntax of sqrt
