对数原本开发来简化复杂的算术计算。
Logarithms had originally developed to simplify complex arithmetic calculations. They designed to transform multiplicative processes into additive ones. Antilog can be found out from Antilog table in the same manner as log, the main difference is that an Antilog table contains numbers from .00 to .99 in the extreme left column. Antilog tables are used to find the antilog of the decimal part.
