**Logarithms & antilogarithms How to find Logs & antilogs**

History: Logarithms were very useful before calculators were invented for example, instead of multiplying two large numbers, by using logarithms you could turn it into addition (much easier!) And there were books full of Logarithm tables to help.... The precise definition of pH is "the negative common logarithm of the activity of hydrogen ion in solution". For practical purposes, the activity is approximated as concentration in moles/L: For practical purposes, the activity is approximated as concentration in moles/L:

Log tables use Log 10 v, so I'll not be writing "Base to" here, i.e. they'll give you base to 10 log's answer. The examples that I'll use below will give you complete clarity about the topic, so they are golden examples & must be seen....

For antilog of negative numbers write the number x as [x] + {x}. [x] will give you the exponent to tha base 10 and antilog of {x} found using antilog table will give you coefficient. For example... Log tables use Log 10 v, so I'll not be writing "Base to" here, i.e. they'll give you base to 10 log's answer. The examples that I'll use below will give you complete clarity about the topic, so they are golden examples & must be seen.

They argue that a better way to handle negative values is to use missing values for the logarithm of a nonpositive number. This is the point at which some programmers â€¦... If you are using log tables, first separate the whole number part and the decimal part of the log ( they are both negative) then add -1 to the whole number part and +1 to the decimal part. (one is called the characteristic and the other is called the mantissa, but I don't remember which is which now) This creates a positive decimal that you can look up in the log table. The negative integer

## How To Find Log Of Negative Numbers Using Log Table

### 14/08/2009Â Â· In the real numbers, there is no such thing as the log of a negative number, as many people have explained. Although to find the log of a negative number we consider the analytic extension of the log function to the complex plane.

- So log, base 100, of 1, is going to be equal to 0. Log base anything of 1, is going to be equal to 0 because anything to the 0 power and we're not talking about 0 here. Anything that is to the power of 0 that is not 0, is going to be equal to 1. Intro to Logarithms. Up Next. Intro to Logarithms
- 14/08/2009Â Â· In the real numbers, there is no such thing as the log of a negative number, as many people have explained. Although to find the log of a negative number we consider the analytic extension of the log function to the complex plane.
- The log tables can be left open and 4-figure logs of numbers to $3$ significant digits can be looked up without having to turn a page. The anti-log tables worked similarly. For example, suppose we want to find the log of $10^{0.5678}$.
- As a general rule, logarithm or anti log functions operate on numbers that are unit less. You can use this above method to modify the formula to solve different desired quantities. The above example may useful for users to understand how to compute antilog for the logarithm number, however, when it comes to online for quick calculations, this anti-log calculator may useful to perform the
