I am hitting a floating-precision problem : one of my results of dividing between Doubles and/or Long gives me 2.8421709430404007E-14 instead of 0.
So I guess I have to use BigDecimals (bigdec more precisely).
My question is :
bigdec convert all other numbers involved in the operation to a suitable type ?*', but /' doesn't seem to exist.If you use any doubles (or floats) in your computation, the final result will be a double.
Otherwise any computation involving BigDecimals will return a BigDecimal result or throw an exception.
Exceptions might be thrown if the result cannot be represented exactly, if some intermediate computation causes long overflow, or if you divide by zero.
+' etc. promote to BigInteger where + would cause integer overflow.
Rounding can be introduced to deal with exact representation issues – see (doc with-precision).
