I need help writing a basic return decimal from string function in Javascript

I have scoured the web for an hour-and-a-half looking for a working, simple string-to-decimal function, and have been depressingly failed. The mentioned string is comprised of letters and numbers. This is meant for a cipher. I would like something like this...

function ConvertDec(str){
    //do conversion
    return decVal;    
}

Were it would be used as such...

decSeed = ConvertDec(seed);
decUserString = ConvertDec(strVal);

These values would then be multiplied to get a full value, which would later be decrypted.

Here's the basics

var str = "123.45";
var dec = parseFloat(str);

console.log(dec); // 123.45
