I have to convert the float to exponential..

0.0000000000000000000000000000000000000000000000000000000000000000000000000000000000000021

Using 

parseFloat(result)

Gives 2.1e-87

But 

10000000

Gives 10000000 (same) but I like to get 100.0e+3 etc..So I used parseFloat(result).toExponential(3); But the problem here is it is truncating everything ev even if it has more values for example 111222333 it makes it as 111.22+3 so while I reconverting as integer I am cannot get the original value..

Is there any javascript function to achieve this or how can I achieve this..

Thanks in advance..

If you use toExponential() with out the parameter, it will not drop the fractions:

console.log( (111222333).toExponential() ); // "1.11222333e+8"

The parameter specifies the amount of digits after the decimal point. If you drop it, it displays as many digits as needed (wrt to the double precision JavaScript uses internally).
