Hi All,
How to conver big number into BigDecimal number in javascript.
eg: var num =777777777777777777777777777777777;
When i tried to use in JS for calculation i don’t have method which support this big number.
If i used parseFloat(num) ; then i got number like 7.77777777777777e12.
Please suggest.

@VITSUSAFeb 26.2020 — @bharatkumar#1615230 Javascript represents it's numbers using double precision floating point numbers. At 16 digits, it will only be able to store the integer component and not the part after the decimal point. You will need a bignum library to use this value.

Success!
