Arithmetic Exceptions

An arithmetic exception arises when an attempted atomic arithmetic operation

does not produce an acceptable result. The meaning of the terms “atomic” and

“acceptable” may vary, depending on the context.

Following are the ﬁve types of IEEE ﬂoating-point exceptions:

• Invalid operation—An operand is invalid for the operation about to be

performed.

program TestRandom(output);

#include "math_p.h"

var

n: integer := 100;

i: integer;

ilb, { Lower bound }

iub: integer; { Upper bound }

ia: array [1..100] of integer;

begin

writeln('Integer linear congruential random number generator');

ilb := I_LCRAN_LB;

iub := I_LCRAN_UB;

i_lcrans_(ia, n, ilb, iub);

for i := 1 to n do

writeln(ia[i]);

writeln('Integer additive random number generator');

ilb := minint;

iub := maxint;

i_addrans_(ia, n, ilb, iub);

for i := 1 to n do

writeln(ia[i]);

writeln('Integer random number shufflers');

i_shufrans_(ia, n, ilb, iub);

for i := 1 to n do

writeln(ia[i]);

end.
