Similarities and differences between logarithm and antilogarithm

logarithm and antilogarithm

You’ve been reading about logarithms and antilogarithms since the first day of school. Depending on your interests, these concepts can be simple or complex. But one thing is certain: once you begin to comprehend, it will begin to save itself in your memory.

The distinction among ln and log is that log denotes base 10 whereas ln denotes base e. For instance, log2 is the log of base 2 and the log of base e is expressed as:

 loge = ln (natural log)

logarithm and antilogarithm

A Ln is the degree to which the base ‘e’ must be increased in order to acquire a number known as its log number. Letter e stands for exponential function. John Napier, who discovered and developed the notion of logarithms, was the first to discover it in the 17th century. Let’s look at the definitions of log and ln before diving into the fundamental differences between the two.

These are broad phrases that are diametrically opposed. If one is in the south, the other is in the west. The similarities and differences between logarithm and antilogarithm will be discussed here. To comprehend these parallels and contrasts, we must first comprehend these words.


Logarithm is the opposite process of exponentiation in mathematics. In algebra and logarithm, exponents are alphabetical notations. If you want to put it simply, the logarithm is the amount of integers that occur in the same factor while multiplying them again. Logarithms can be computed for any positive number, even zero. It is negative for logarithms of values between 0 and 1, and positive for logarithms of values greater than 1. It’s impossible to calculate the logarithms of zero or any other negative number. You can calculate logarithm easily by using a log calculator online to get your results quickly.


You can define this function as the antilog of the logarithm (log bz). In this case, bz is the antilogarithm in base b of Z.

  • Step one is separating the mantissa portion of the number from its characteristic portion of the number.
  • Use the antilog table to determine a value for the mantissa based on the antilog table. Two of the mantissa’s first digits define the number of rows, while the third digit expresses the number of columns. Note this number.
  • There are also columns in the antilog table that provide the mean difference. Fourth-digit column numbers are used for similar mantissa rows. Note this number.
  • Add the values that you’ve just gotten.
  • Assign a value of 1. Where to insert the decimal point is indicated by this value. That many digits to the left of the decimal point are where the decimal point is located.

You can also calculate an antilog calculator with steps by using an anti logarithm calculator easily.

Log vs. Ln

It’s not always practicable to deal with numbers that are too big or too little. We use logarithms to change the shape of a number to make long, tedious, and difficult calculations simple. Antilog can be used to restore the original form of the modified number. The inverses of each other are logarithms and anti-logarithms. Let’s take a closer look at logs and antilog.

  1. Ln is a base e logarithm, while Log is a base 10 logarithm.
  2. Logarithm is referred to as a common logarithm, whereas ln is referred to as a natural logarithm.
  3. The common log is denoted by the letter x, whereas the natural log is denoted by the letter e. (x)
  4. The natural logarithm’s exponential form is ex =y, but the ordinary logarithm’s exponential form is 10x =y
  5. “In order to get y, what number should we multiply by 10?” is the question for the common logarithm. The natural logarithm’s interrogative phrase is “At which number should we increase Euler’s fixed amount to get y?”
  6. When compared to ln, it is more extensively employed in physics. In physics, logarithms are applied to the base, hence ln is rarely employed.
  7. It is expressed mathematically as logarithm base 10, whereas this is expressed mathematically as logarithm base e.


You now have a general understanding of how log and antilog processes work. If you want to be a math expert, you should grasp the fundamentals of math. You will become familiar with them and find it convenient to utilize them if you learn them by practicing with a log calculator. Above, we covered the differences and similarities between logarithm and antilogarithm. I hope you find this information helpful and that you will use it in your math and research.
