// ----------------------------------------------------------
// A short snippet for detecting versions of IE in JavaScript
// without resorting to user-agent sniffing
// ----------------------------------------------------------
// If you're not in IE (or IE version is less than 5) then:
//     ie === undefined
// If you're in IE (>=5) then you can determine which version:
//     ie === 7; // IE7
// Thus, to detect IE:
//     if (ie) {}

Sass/Less Comparison

In this document I am using Sass's SCSS syntax. You can choose to use the indented syntax in sass, if you prefer it, it has no functional differences from the SCSS syntax.

For less, I'm using the ruby version because this is what they suggest on the website. The javascript version may be different.

        av = n.appVersion,
        tv = parseFloat(av);
    
    if(ua.indexOf("Opera") >= 0){state.isOpera = tv;}
    state.isKhtml = (av.indexOf("Konqueror") >= 0) ? tv : 0;
