All of the calculations on the LMNO Engineering, Research, and Software, Ltd., website have been coded using double precision and checked against known results. Even though some of the calculations show output fields to eight significant figures to save space while some show 16 significant figures, all internally perform computations in double precision. LMNO Engineering is confident that the programs work as intended; however, LMNO Engineering cannot be held responsible for any negative consequences of using the programs. Our calculations are written in the PHP programming language.

Error messages within a calculation
If a calculation divides by zero, a "NAN" message will be printed in an output field. This means a value of infinity was computed. Division by zero is usually due to a number being typed incorrectly, such as 0.0 for density on the Energy Equation page.
