Decimal values gets round off automatically

When i assign 99999999999.999999 to a variable, it gets round off to 100000000000, and when i remove one 9 from the value , the last digit becomes 8.

like,

9999999999.999999 = 9999999999.999998
99999999999.99999 = 99999999999.99998

kindly help me to resolve this

Numbers in ECMAScript (Javascript) are internally represented by double-precision floating-point. When setting a number, it actually is assigned the nearest representable double-precision value, which is 100000000000 in this case.
