How to NOT leave the javascript convert my number to exponential notation?

[Felipe Oliveira Gutierrez]

I hava a number too large and when i plus it with another number the result is showed in exponential notation on my screen.

You are probably better off with the exponential notation.

Javascript loses precision after 15 or so digits.

9284476546528123456781 may be rounded to
9284476546528124000000, and

0.00000000009284476546528123456781 to
0.00000000009284476546528124

If you need more precision you can use a javascript big integer library,
or hand off the calculations to a library on the server.

If you just want to replace the notation with the rounded number,
you can do it with a replace operation on the string value of the number.

Numbers smaller than zero will be returned with the zeroes in front of the first significant digit,
big numbers will add zeroes to the end.

Number.prototype.todigits= function(){
    var tem='', z, d, s= this.toString(),
    x= s.match(/^(\d+)\.(\d+)[eE]([-+]?)(\d+)$/);
    if(x){
        d= x[2];
        z= (x[3]== '-')? x[4]-1: x[4]-d.length;
        while(z--)tem+='0';
        if(x[3]== '-'){
            return '0.'+tem+x[1]+d;
        }
        return x[1]+d+tem;
    }
    return s;
}

//TEST
var n= 0.00000000009284476546528123456781,
n2= 9284476546528123456781;
alert(n+'\n'+n.todigits()+'\n'+ n2+'\n'+n2.todigits())
 
returned value: (String):
9.284476546528124e-11
0.00000000009284476546528124
9.284476546528124e+21
9284476546528124000000

Javascript loses precision after 15 or so digits.

all IEEE 754 floats do that. (that is the only number type in JavaScript)
