I need to recreate the following formula in java:

INT((A2^3 + B2^3) / 100)) + MOD((A2^3 + B2^2), 100)

Can someone show me how to do this in java?


-Thanks

What do you mean by int? you mean integrate or what?

Mod is % in java. so int i = 10 %5 = 0. 11 % 5 = 1 (if i remember
correctly)

To do powers you simply do Math.pow() look it up in your java api docs.
Look for the Math class.

int answer = ((int)(pow(a2,3) + pow(b2,3)) / 100) +
((pow(a2,3) + pow(b2,2)) % 100);

All you need to do is to spend 10 mins reading your textbook, rather than
posting your homework and waiting somebody to do it for you.

Nitpick:

% in Java is actually remainder, not Modulus.
True Modulus produces a result from 0 to the divisor-1.
% can produce negative results.

"the % operator is not a true mod operator, but computes the remainder,
which may be negative"
