php e – Using M_E and exp() Function to Get Euler’s Constant e

To get the value of Euler’s Constant e in php, the easiest way is to use the php constant M_E. M_E returns the value 2.718281828459.

echo M_E; // 2.718281828459

You can also use the php exp() function. exp(1) returns the value 2.718281828459.

echo exp(1); // 2.718281828459

In php, we can easily get the value of e for use in various equations and applications with the php predefined constants.

To get the value of the constant e in your php code, you just need to call the predefined constant M_E.

Below is an example of how to get Euler’s Constant in php using the predefined constant M_E.

echo M_E; // 2.718281828459

Using the php exp() Function to Get Euler’s Constant e

In php, there are a number of great functions which allow us to do various calculations included in the built-in php math functions.

To get the value of the constant e in your php code, we can also call the exp() function and pass ‘1’ to it to raise the constant e to the first power.

Below is an example of how to get Euler’s Constant in php with the exp() function.

echo exp(1); // 2.718281828459

Hopefully this article has been helpful for you to understand how to get the value of e from the php constant M_E and exp() function.
