When precise computation is necessary, carefully and methodically evaluate the cumulative error of the computations, regardless of whether decimal or binary is used, to ensure that the resulting error is within tolerances. Consider using numerical analysis to properly understand the numerical properties of the problem. A useful introduction is Goldberg 91.
Risk Analysis
Using an alternative representation besides floating point may allow for more precision and accuracy for critical arithmetic.
