log()

Compute natural logarithm.

The log() function in math is a function that returns the natural logarithm (base e) of a number. The natural logarithm is the logarithm to the base e, where e is the mathematical constant approximately equal to 2.71828. It is the inverse of the exponential function. The input to the function is a number and the output will be a float.

For example, log(e) would return 1, and log(10) would return 2.30258509.

The log() function is commonly used in mathematics, physics, engineering and other fields, such as solving equations involving exponentials and logarithms, as well as in various algorithms and data analysis.

Syntax

log(x);

Parameters

x Value whose logarithm is calculated.
Return Value Natural logarithm of x.

Examples

result = log(10);

result:

2.30258509
