/ and /= operators
Used to divide two numbers and return a floating-point result. The compound form /= divides-and-assigns in one step.
Syntax:
result = number1 / number2
variable /= number (twinBASIC)
- result
- Any numeric variable.
- variable
- (twinBASIC) Any numeric variable or writable property.
- number, number1, number2
- Any numeric expressions.
The data type of result is usually a Double or a Double variant. The following are exceptions:
| If | Then result is |
|---|---|
| Both expressions are Byte, Integer, or Single | A Single unless it overflows its legal range, in which case an error occurs. |
| Both expressions are Byte, Integer, or Single variants | A Single variant unless it overflows its legal range, in which case result is a Variant containing a Double. |
If one or both expressions are Null expressions, result is Null. Any expression that is Empty is treated as 0.
Dividing by zero is an error for integral types; for Single and Double it follows the IEEE-754 rules (positive infinity, negative infinity, or NaN). Use \ for truncating-integer division and Mod for remainder.
Compound assignment
x /= y is the twinBASIC shorthand for x = x / y. The left-hand side is evaluated once; the result follows the same type-promotion and Null / Empty rules described above. /= is a statement, not an expression --- it does not produce a value.
Dim Value As Double = 100
Value /= 4 ' Value is now 25.
Value /= 5 ' Value is now 5.Example
This example uses the / operator to perform floating-point division.
Dim MyValue
MyValue = 10 / 4 ' Returns 2.5.
MyValue = 10 / 3 ' Returns 3.333333...
