A function giving the base-10 logarithm of its argument.
X = LOG(Y)
This function calculates the common (base 10) logarithm of its argument. Inverse logarithms (anti-logs) can be calculated by raising 10 to the power of the logarithm. For example, if x=LOG(y) then y=10<sup>x</sup>.
Logarithms are 'traditionally' used for multiplication (by adding the logarithms) and division (by subtracting the logarithms). For example,
10 log1=LOG(2.5) 20 log2=LOG(2) 30 log3=log1+log2 40 answer=10^log3 50 PRINT answer
