Is there a simple way of pressing a button on a flash calculator to calculate the square root (sqrt)? I cant find anything about it.

for example

```auto
 
// Tangent of the angle in degree

function Dotan () {
 if (display == 90) {
  display = "Infinity";
 } else {
  display = Math.tan((display*Math.PI/180));
 }
 refresh();
}

```

```auto
 
//On release function
 
on (release) {
if(off_flag==false) {
 if (setflag == true) {
display_flag = 0;
  Status = "atan";
  Doatan();
 } else {
display_flag = 0;
  Dotan();
  Status = "tan";
 }
}

```

}

But with sqrt?  
Thank you for any help
