term1 operator1 term2 operator2 term3
is
encountered, and operator2 has a higher precedence than operator1, the subexpression (term2 operator2 term3) is evaluated
first. The same rule is applied repeatedly as necessary.
Note, however, that individual terms are evaluated from left to right in the expression (that is, as soon as they are encountered). The precedence rules affect only the order of operations.
Examples:
A+5 -> '8'
A-4*2 -> '-5'
A/2 -> '1.5'
0.5**2 -> '0.25'
(A+1)>7 -> '0' /* that is, False */
' '='' -> '1' /* that is, True */
' '=='' -> '0' /* that is, False */
' '¬=='' -> '1' /* that is, True */
(A+1)*3=12 -> '1' /* that is, True */
'077'>'11' -> '1' /* that is, True */
'077' >> '11' -> '0' /* that is, False */
'abc' >> 'ab' -> '1' /* that is, True */
'abc' << 'abd' -> '1' /* that is, True */
'ab ' << 'abd' -> '1' /* that is, True */
Today is Day -> 'TODAY IS Monday'
'If it is' day -> 'If it is Monday'
Substr(Day,2,3) -> 'ond' /* Substr is a function */
'!'xxx'!' -> '!XXX!'
'000000' >> '0E0000' -> '1' /* that is, True */
-3**2 == 9 /* not -9 */
-(2+1)**2 == 9 /* not -9 */
2**2**3 == 64 /* not 256 */
