> For decimals, overflows can occur at two places :
>  # input array can have values that are outside the bound (eg. > 38 digits)
>  # When an operation can result in overflows. eg. add of two decimals of (38, 6) can result in an overflow, if the input numbers are very large.
> In both the above cases, just verifying that an overflow occurred can be a perf overhead. We should do this based on a conf variable.
