How to perform a successful round in AX from real to integer?…
Well, the answer is: use the function decround.

static void Job1(Args _args)
{
    int i, ii;
    real r = 334.55, r2 = 334.14;
    ;

    i = decround(r, 0);
    ii = decround(r2, 0);

    // It shows 335, 334
    info(strfmt("%1, %2", i, ii));
}
