Casio does and so does sharp.

In the early days of calculators, there was no precedence. All operations
were done left to right, as that saved registers.

Which calculators have a dot operator?

I discovered this when solving one of those trivia questions.
The question was to find out what
36 divided by 2.(3)+ 4
can't get the division symbol on this PC.
Correct answer should be to write this as
36/2 X 3 + 4 =58
a computer would interpret it thus. Type that into a calculator and you will get 58 if you type
36 divided by 2X(3) + 4
where it doesn't matter whether there is a bracket round the 3 or not.
Now in your calculator put
36 divided by 2.(3)+4
where you use the dot operator (assuming your calculator supports this) instead of multiply. You get 10.
It appears that the dot multiply takes the brackets around the 2 and 3 (2X3) and then does the division into 36. You must have the brackets round the 3 or it takes the number as 2.3 of course.
