Concatenate string and var less css

Question

Can anyone please tell me how to concatenate a var and a string in LESS so I don\'t have the space between them?

I have the following code:

.text(@si

In a case you need to use it in combination with CSS function (eg. calc), here is one way:

@width: 12;
width: %(~"calc(33%% - %dpx)", @width);

Outputs:

width: calc(33% - 12px);
