LOGARITHMS
Natural logarithms are provided by the function
LOG(number or variable).
PRINT LOG ( 10) displays t2.30258509'
PRINT LOG ( 5000) displays t8.5171932'
The antilogs of natural logarithms are calculated
by EXP(N). Try:
PRINT EXP(LOG(100»
The answer is 100. The Atari actually prints
99.9999976 - the calculation is not quite accurate.
Logs can be used to calculate roots. This program
finds the cube root of 8.
10 A = 8
20 R
= LOG(A)/3
30 PRINT EXP(R)
