Re: [Help-jel] expression problem

[Konstantin L. Metlov]

Dear Niket,

This your expression gives unexpected result because of an integer
overflow, which is unrelated to JEL. The problem is that 222222*10000 is
not representable by 32-bit Java type "int" (whose largest value is
2147483647=0x7fffffff).  When such a big numbers are encountered (with
more than 32 bits required for their representation) the highest not 
fitting bits are discarded.

To solve the problem you can either use a java "long" type

java Calculator 222222*100000L
22222200000                  ^
                             |
                             +---- please note this.

(which holds 64 bits and whose maximum value is
9223372036854775807=0x7fffffffffffffff), or, if you expect even bigger
numbers in your application, "double" type

java Calculator 222222*100000.0
2.22222E10

. The arithmetics with "double" numbers is not exact and the least 
significant bits in the mantissa can be lost.

The support of arbitrary-precision arithmetics is out of scope of the 
current version of JEL. Such support can be added, though (for a fee, if 
someone needs it within a specified timeframe).

With the best regards,
                        Konstantin.
