What is E in C programming?

The C exp function is one of the Math Functions, used to return E raised to the power of a given value or specified expression. Here, E is Euler’s number, and it is approximately equal to 2.71828. The basic syntax of the exp in C Programming is double exp(double number);

How do you use Ceil?

The ceil() function takes a single argument and returns a value of type int . For example: If 2.3 is passed to ceil(), it will return 3. The function is defined in header file.

How do you find PI in C?

Using Constants in C: One is by using using the preprocessor directive ‘#define’ to make ‘PI’ equal to 3.142857. The other uses the key work ‘const’ to define a double called ‘pi’ equal to 22.0/7.0.

What is the purpose of the math h header?

The math.h header defines various mathematical functions and one macro. All the functions available in this library take double as an argument and return double as the result. This macro is used when the result of a function may not be representable as a floating point number.

Is there a type-generic macro version of the log function?

Header provides a type-generic macro version of this function. This function is overloaded in and (see complex log and valarray log ).
