 4. Math Operations |
Tests whether the two values are equal.
Results is 1 if test is true, 0 if test is false.
70 a=0
72 do
74 PRINT a
76 a=a+1
78 while a == 1
Output:
0 1
[ index | memory | math | statements | variables | registers | assembler ]
| 4.02 | ! = | Boolean Not Equals |
Tests whether the two values are not equal.
Results in 1 if test is true, 0 if test is false.
1 a=0
5 do
10 PRINT a
15 a=a+1
20 while a != 3
Output:
0 1 2
[ index | memory | math | statements | variables | registers | assembler ]
| 4.03 | > | Boolean Greater Than |
Tests whether the first value is greater than the second value.
Results in 1 if test is true, 0 if test is false.
1 a=0
5 do
10 PRINT a
15 a=a+1
20 while a > 3
Output:
0
[ index | memory | math | statements | variables | registers | assembler ]
Tests whether the first value is less than the second value.
Results in 1 if test is true, 0 if test is false.
1 a=0
5 do
10 PRINT a
15 a=a+1
20 while a < 3
Output:
0 1 2
[ index | memory | math | statements | variables | registers | assembler ]
| 4.05 | >= | Boolean Greater Than or Equal To |
Tests whether the first value is greater than or equal to the second value.
Results in 1 if test is true, 0 if test is false.
PRINT 5 >= 3
Output:
1
[ index | memory | math | statements | variables | registers | assembler ]
| 4.06 | <= | Boolean Less Than or Equal To |
Tests whether the first value is less than or equal to the second value.
Results in 1 if test is true, 0 if test is false.
1 a=0
5 do
10 PRINT a
15 a=a+1
20 while a <= 3
Output:
0 1 2 3
