This is entirely unnecessary. y isn't a string, it's a number.
parseFloat takes a string, and parses it to a number. So, what happens
is that y is autocast into a string and then that string is parsed
into a float.

toString is a method, not a function. Since you aren't specifying an
object, it will be resolved as a variable. Since properties of the
window object are also variables in the global scope, you're
effectively calling window.toString here.

Naturally. Nothing else is to be expected.


var
    a="12.75", // a is of type string
    b=parseFloat(a), // b is of type number
    c=Number(a), // c is of type number
    d=String(b), // d is of type string
    e=c.toString(), // e is of type string
    f=''+b, // f is of type string
    r=/\./g;

alert(d.replace(r,'_')); // ==> 12_75
