The meaning of constant e is the limit value that can be reached by doubling the growth continuously in unit time, which is of great significance in physics, biology and other natural sciences, and is generally expressed by lnx. Logx is also commonly used in mathematics to represent natural logarithm. In order to avoid confusion with the commonly used logarithm lgx with the base of 10, "㏒ex" can be written as the full name. The meaning of constant e is the limit value that can be achieved by doubling the growth continuously in unit time.
Extended data:
E is widely used in science and technology, and the logarithm with the base of 10 is generally not used. Taking e as the base can simplify many formulas, and it is the most "natural", so it is called "natural logarithm" E is approximately equal to 2.7 1828.
For example: log (1) = 0; loga(a)= 1； logab×logba = 1； -logaa/b=logcb/a .
