Atari XL

Functions
67
The answer is 2, because 2 cubed (2*2*2) is 8.
(Again the Atari is not quite accurate, printing
1.9999999.)
This program calculates fifth roots.
10 N = 243
20 R = LOG(N)/5
30 PRINT EXP(R}
The program will display (3' (actually 2.99999993),
because 3 to the power 5 (3/\5 or 3*3*3*3*3) is 243.
Base ten logarithms are catered for by the function
CLOG. The antilogs can be calculated by using the
formula:
Antilog zz: 1olog
So, if:
TENLOG = CLOG (A)
Then:
A = lOI\TENLOG
RANDOM NUMBERS
The Atari XL has a function which provides
random numbers. The function is RND(X), which
prints a number between 0 and 1. The 'seed' value
-X- can be any number or letter, but does directly
influence the value of the random number that
results. Try PRINTing RND(I) a few times. You
will get a different number each time.
