when == are still two equal signs

Posted 9 years ago

Sometimes when I type ==, it does not become one symbol. They are still two equal signs. In this case, does it work as the normal == symbol? Thank you.

Hit a white space behind the repeated equal sign to get them into a single symbol and read about Equal; because there is also SameQ consisting of three consecutive equal signs the white space is needed to start symbol conversion.

There is no white space after ==. One example is ca[1] == 1, which has two equal signs. I copied it from my notebook. But if I copy the equation from here to my notebook, it becomes the normal == symbol. Therefore, you cannot try it.

I tried the double equal signs and they make no difference. In other words, they act like the normal == symbol.
