Many logarithm tables give logarithms by separately providing the characteristic and mantissa of "x", that is to say, the integer part and the fractional part of log("x"). The characteristic of is one plus the characteristic of "x", and their significands are the same. This extends the scope of logarithm tables: given a table listing log("x") for all integers "x" ranging from 1 to 1000, the logarithm of 3542 is approximated by
