In MariaDB, LN()
is a built-in function that returns the natural logarithm of its argument. In other words, it returns the base-e logarithm of its argument.
The number e, also known as Euler’s number, is a mathematical constant approximately equal to 2.71828.
LN()
is the inverse of EXP()
, and it’s the same as using LOG()
with the single argument syntax.
