Arithmetic expressions
When no parentheses are present, arithmetic expressions are evaluated from left to right, with multiplication and division having a higher priority than addition and subtraction.
| Highest | NOT, - (unary) |
*, /, MOD |
|
+, - |
|
<, <=, >, =, >=, > |
|
| Lowest | AND, OR, XOR |
The arithmetic operators, +, -, *, and /, work in the expected fashion, however, the result of arithmetic on type BYTE, WORD or INT cannot have a fractional result. Therefore 5 / 2 evaluates as 2, not 2.5 (any fraction is always discarded). However, 5.0 / 2.0 evaluates as 2.5, because the presence of the decimal point tells the compiler that the numbers are FLOAT.
PRINT 5/2 ' Outputs 2 PRINT 5.0/2.0 ' Outputs 2.5
