Operator precedence?

[agraham]

Is this an operator precedence problem or just a "feature"?


this causes a compilation "syntax error"
Msgbox(time/1000 & " Seconds", "Elapsed time")

but this is OK
Msgbox((time/1000) & " Seconds", "Elapsed time")

Agraham, remember this http://www.b4x.com/forum/beta/6541-listview.html#post38240 ? it is the same issue.

It IS the same issue but it has just occurred to me that it is possibly an operator precedence problem. For example my BasicLib library can evaluate an expression like that without requiring the parentheses to force early evaluation of the numeric sub-expression because in it the & operator has a lower precedence than the / operator.

It may be that the compiler uses a different expression evalutor for string rather than numeric expressions which doesn't recognise precedence.

B4A compiler doesn't allow string operators and numeric operators to be combined (without parentheses).
