As a programmer, when writing code I like to clearly distinguish using function aliases like log2 , log10 , loge. Or a single overloaded function log , which when given two parameters takes the first as the base, like log 2,x. Add a comment. The difference is which number is the base. Michael Hardy Michael Hardy 1. If calculating or programming, check a test result before making assumptions. And in the latter case, it may be best to simply ignore a language's built-in log function and use your own so that your code is more portable.

It is also called the logarithm of the base e. Here, the constant e denotes a number that is a transcendental number and an irrational which is approximately equal to the value 2.

Quotient Rule. The natural log of the division of x and y is equal to the difference of the ln of x and ln of y. Reciprocal Rule. The natural log of the reciprocal of x is equal to the opposite of the ln of x. Power Rule. The natural log of x raised to the power of y is equal to y times the ln of x. We have discussed the log and ln rules above.

Log values from 1 to 10 to the base e are given below-.
