Arithmetic operation is an operation involving arithmetic operators. Arithmetic Operators in Visual Basic is:
- plus (+)
- minus (-)
- times (*)
- for (/)
- rank (^)
- residual for (mod)
Arithmetic operators generally operate on two operands. For example the expression 2 + 2, means:
2 is the first operand
Arithmetic operator + is added
2 is the second operator.
But in some respects, especially operators + and less operate on one operand, such as giving the value of +5 (positive 5) or -5 (negative five).
In visual basic arithmetic operators workmanship has set the degree of workmanship as follows:
Operator Degrees
^ 1
* / Mod 2
+ - 3
operators who have the same degree will be done starting from the left.
For example there is the statement:
A = 2 + 2-5
seen that there are two of the arithmetic operators + and -. It was decided that the operators + and - have the same degree of craftsmanship so that the operator of the most left will done first. Thus the order of execution of the statement are:
1. 2 + 2 provides the results of 4
2. 4-5 give the results -1
3. -1 was given to a variable A
Suppose there are statements like the following:
A = 2 + 5 * 10, then the process sequence is
1. 5 * 10 = 50
2. 2 + 50 = 52
3. 52 were given to A
We consider the operator * is done in advance rather than operator +. How about if we change the order of workmanship want where desired operator + higher degree of workmanship of the operator *. To do this on a operator operators + plus open parenthesis and close parenthesis so that the form of a statement becomes:
A = (2 +5) * 10, then the order of the process becomes:
1. 2 + 5 = 7
2. 7 * 10 = 70
3. 70 were given to A
If there are parentheses within parentheses, the innermost parentheses to be done first. For example there is a statement as follows:
A = 7 * ((2 +5) * 10), then the sequence of the process becomes:
1. 2 + 5 = 7
2. 7 * 10 = 70
3. 7 * 70 = 490
4. 490 were given to A
Suppose there is a statement as follows:
A = (2 + 5) * 10-15 + 7 ^ 2, then the order of execution of the statement are:
1. 2 + 5 = 7
2. 7 ^ 2 = 49
3. 7 * 10 = 70
4. 70-15 = 55
5. 55 + 49 = 104
6. The value 104 was given to A
