C++ Math expm1()
The function computes the exponential 'e' raised to the power a given number minus 1.
Suppose a number is 'x'
Note: The return_type can be float, double or long double.
x: It is the value of the exponent.
It returns 'e' raised to the power x minus -1.
Let's see a simple example
Value of x is : 6 expm1(x) = 402.429
In this example, the value of x is 6. The expm1() function computes 'e' raised to the power 6 minus one.
Let's see another simple example
Value of x is : 9.8 expm1(x) = 18032.7
In this example, value of x is 9.8. The expm1() function computes 'e' raised to the power 9.8 minus one.
