Arithmetic operations
1.1
Arithmetic operators
Operators
Usage Example
Meaning
+
A+B
Adds A to B
-
A-B
Subtracts B from A
*
A*B
Multiplies A by B
/
A/B
Divides A by B
^
A^B
Obtains the B exponent of A (exponent operation)
-
-A
Reverses the sign of A
MOD
A MOD B
Obtains the remainder A divided by B
When a "remainder" (MOD) operation involves real numbers,
the decimal value is rounded off to
the nearest whole number which is then converted to an integer
before the calculation is executed.
The result represents the remainder of an integer division operation.
Examples: A=15 MOD 2
→
A=1(15/2=7....1)
A=17.34 MOD 5.98
→
A=2(17/5=3....2)
1.2
Relational operators
Relational operators are used to compare 2 values. If the result is "true", a "-1" is obtained. If it is
"false", a "0" is obtained.
Operators
Usage Example
Meaning
=
A=B
"-1" if A and B are equal, "0" if not.
<>, ><
A<>B
"-1" if A and B are unequal, "0" if not.
<
A<B
"-1" if A is smaller than B, "0" if not.
>
A>B
"-1" if A is larger than B, "0" if not.
<=, =<
A<=B
"-1" if A is equal to or smaller than B, "0" if not.
>=, =>
A>=B
"-1" if A is equal to or larger than B, "0" if not.
Examples: A=10>5
→
Since 10 > 5 is "true", A = -1.
• When using equivalence relational operators with real variables and real arrays, the desired
result may not be obtained due to the round-off error.
Examples: .............................A=2
B=SQR(A!)
IF A!=B!*B! THEN...
→
In this case, A! will be unequal to B!*B!.
