The **LOGE** (pronounced “log-e”) procedure returns the natural logarithm of a numeric *expression*. The natural logarithm of a value is the power to which **e** must be raised to equal that value. The value of **e** used internally by the Clarion library for these calculations is 2.71828182846.

Return Data Type: | REAL |

**Example:**

** !LOGE(2.71828182846) returns 1**

** !LOGE(1) returns 0**

**LogVal = LOGE(Val) !Get the natural log of Val**
