any idea if there is any support available for big decimal no.s in

javascript?

I have found the ECMA specification (ECMA-262) which mentions that it

supports double-precision 64-bit format IEEE 754 values. Refer to

4.3.20 section of Ecma-262.pdf attached.

Searching further for IEEE 754 specs, it has been mentioned that the

finite positive and finite negative numbers furthest from zero

(represented by the value with 2046 in the Exp field and all 1s in the

fraction field) are ±1.7976931348623157×10308

(1.7976931348623157e+308). Refer to the 3.2.2 section of ieee754.pdf

attached.
