Return Type − This function returns a non-zero value if the argument is greater than -1 else it will return a non-numeric value.
Example
Input
a = 20.34
Output
3.06058
Input
a = 0.0
Output
0
Example
#include <cmath> #include <iostream> using namespace std; int main(){ double ans = 20.34; double temp; temp = log1p(ans); cout << "value of log1p(" << ans << ") is: "<<temp<< endl; ans = 0.0; temp = log1p(ans); cout << "value of log1p(" << ans << ") is: "<<temp<< endl; return 0; }
Output
value of log1p(20.34) is: 3.06058 value of log1p(0) is: 0
