How to Calculates the exponent of e in PHP ?

In PHP, we can calculate the exponent of e using the exp() function. The exp() function returns the value of e raised to the power of a given number.

Syntax:

exp(number)

Example:

$num = 2;
$exp = exp($num);
echo "Exponent of e raised to the power of $num is: $exp";

Output:

Exponent of e raised to the power of 2 is: 7.3890560989307

Another method to calculate the exponent of e is by using the pow() function. We can use the M_E constant in PHP to represent the value of e.

Syntax:

pow(M_E, number)

Example:

$num = 3;
$exp = pow(M_E, $num);
echo "Exponent of e raised to the power of $num is: $exp";

Output:

Exponent of e raised to the power of 3 is: 20.085536923188
