#### Formula:

n = - ( Log( x )) = Log( 1 / x )
**Where,**
n = Negative Log
x = Value of x
**Negative logarithm:** It means the number of times we divide 1 by the base to achieve the log value. The negative of log_{y} (x) is _{y}log (1 / x).

**Online Negative Log Calculator:** Make use of this online logarithmic calculator to find the same with ease. This negative logarithmic calculator tool computes the values by finding the log value for the inverse of 'x' (1/x). Also, we have provided a simple example problem with detailed steps which would help you in understanding the calculation concept with ease.

### Example

#### Negative Log

**Calculate the value of - ( log**_{2} (2) )

n = log_{2} ( 1/2 )

= log_{2}(1) - log_{2}(2) (Since log(a/b) = log(a) - log(b))

= 0 - 1

n = -1

Hence the value of negative log_{2} (2) is -1
