exp math
The C++
exp()function returns the exponential (Euler’s number) e raised to the given argument. It is defined in the<cmath>header file.
exp in math
Syntax
exp(x);
Parameters
The exp() function takes a one argument which can be any value i.e. negative, positive or zero.
Return value
Returns the value in the range of [0, ∞].
If the magnitude of the result is too large to be represented by a value of the return type, the function returns
HUGE_VAL(orHUGE_VALForHUGE_VALL) with the proper sign, and an overflow range error occurs.
exp
exp() prototype [As of C++ 11 standard]
double exp(double x); float exp(float x); long double exp(long double x); double exp(T x); // For integral type
exponential in c
Example 1 : C++ exp()
#include <stdio.h> #include <math.h> int main () { double param, result; param = 5.0; result = exp (param); printf ("The exponential value of %f is %f.\n", param, result ); return 0; }
Output
The exponential value of 5.000000 is 148.413159.
c exp
Example 2 : C++ exp()
#include <iostream> #include <cmath> using namespace std; int main() { long int x = 4; double result; result = exp(x); cout << "exp(x) = " << result << endl; return 0; }
Output
exp(x) = 54.5982
