For example log 48 = 1.68124; log 49 = 1.69019;

ln 49 = 3.89182; ln 48 = 3.87120;

The number in the answer to the left of the decimal point is call the characteristic

and the number to the right is the mantissa.

So in the case of ln 49 = 3.89182 the 3 is the character and .89182 is the mantissa.

Why does the answer for log 48 differ from ln 48? answer
