&rt meaning

Hi all, I read through some projects and I saw '' &rt ''. Can anyone help me to explain what it mean? Thanks a lot!

can we have a bit more context?

& is bitwise AND and can be used to extract values out of bigger values, like colours:

https://processing.org/reference/bitwiseAND.html

but without more context it's hard to say...

void edges() {

    // x-direction
    if (loc.x &rt; world) {
      loc.x = 0;
    } 
    else if (loc.x < 0) {
      loc.x = world;
    }

    // y-direction
    if (loc.y &rt; world) {
      loc.y = 0;
    }  
    else if (loc.y < 0) {
      loc.y = world;
    }

    // z-direction
    if (loc.z &rt; 0) {
      loc.z = -world;
    } 
    else if (loc.z < -world) {
      loc.z = 0;
    }
  }
}

that looks like mangled html markup - you have to escape less than and greater than in html because that's what denotes the start of html tags.

but that's usually & lt; and & gt; respectively.

rt looks like an error.

but you can guess the meaning - that code is checking to make sure values are within limits.

so i'd say that's mangled & gt; for > (maybe someone confused 'less than' and 'greater than' for 'left tag' and right tag')

Only the < is needed for HTML! >-)

&rt; should be replace with > so it seems.
