Exponential to Number.
When i am doing rounding of the value i am getting the o/p like 2.2e4.
I have to display this value in decimal value(2.0002) not in exponential.
Can any one please help me to resolve this issue.?

Um...you apparently don't understand what 2.2e4 means.
2.2e4 is the same as 22000.0
2.2e-4 would be the same as 0.00022
I'm actually surprised that you would ever get "2.2e4". Are you sure it wasn't "2.2e-4"???
Anyway, you *can* control the display using toFixed( n ) where n is the number of digits to be shown after the decimal point.
So:And so on.Code:var num = 2.2e4; alert( num.toFixed(2) ); // would show 22000.00 var num = 2.2e-4; alert( num.toFixed(2) ); // would show 0.00 -- because the 0.00022 "rounds" to just 0.00 var num = 2.2e-4; alert( num.toFixed(6) ); // would show 0.000220
