how to findout the log value of numbers like.. 0.0321, 0.00428, 0.00021 etc.
***
For most calculators I know, you can directly plug in the numbers above to get the log value using the LOG key. Note that for logs with arguments between zero and one, (0,1), are always negative.
An alternate way is to convert the numbers above to powers of 10.
For example:
0.00428=4.28*10^-3
log(0.00428)=log(4.28)+log(10^-3)=0.631444-3=-2.368556
with direct plug in:
log(0.00428)=-2.368556
