...to base 2 equals 1.5850." The subscript indicating the base is usually omitted when 10 is the base. The integral part of a logarithm is called its characteristic, and the decimal part its mantissa. Thus, in 1.5850, which is the logarithm of 3 to base 2, the 1 is the characteristic and the .5850 is... | |
