- The response field will not clear when a comma is entered, separating two numbers. Commas will disappear and any numbers that were separated will come together. For example 5,8 will change to 58. The Active-X grids for the standard and sample replicate data are set up to clear an entry containing invalid characters and to only clear commas for numbers like 200,306. If a comma is inadvertently entered as a decimal point, the value may be interpreted incorrectly.
- A leading or trailing dollar ($) sign will not clear the response field. Leading and trailing dollar signs will be dropped. Any other placement of a dollar sign will clear the response field.
- Parentheses bracketing a unsigned number in a response field will convert the number to a negative value and drop the brackets. Parentheses bracketing a signed number (+nn/-nn) in a response filed will clear the field.
- A negative standard response will not calculate results in the sample set. This will produce an amount found and the percent found results of zero. Geneva procedures specify that negative standard responses for specific raw material calculations are to be calculated by hand. Data entry and calculations performed in GenevaCalc are to be manually checked for accuracy.
- The equation evaluation fields do not use brackets, [ ] { }, for formula syntax. Parentheses are sufficient for the formula syntax for laboratory analyses performed at Geneva.
- The high and the low fields for the standard calibration sets, sample subset statistics and sample set statistics were set up with boundary values for programming logic for the maximum and minimum calculation functions. The maximum and minimum values for the high and low fields needed to be set in the opposite direction of zero. These setting are -1E+24 for the high and 1E+24 for the low. If all the replicate values are greater than the boundary limits, the high or low value will default to -1E+24 for the high and 1E+24 for the low. For example if a calculation produces an amount found of 3.1E+30 mg the high statistic is 3.1E+30mg but the low would be 1.0E+24 mg. The upper and lower claims for current product lines at Geneva are 1000mg and 0.025mg respectively.
- The exponential notation for the percent found statistics (average, high, low and total) do not display on the report or screen if the value exceeds 15 figures. The greatest number of significant figures used is 9.
- The replicate fields (sample weight, response and internal standard response) on the report are limited to a minimum of 16 numeric characters. If the number in the application field exceeds the number of spaces, they will not be displayed on the report. The upper limit of characters that are entered into a replicate field for product release analysis is 11.
- Formulas entered in the evaluation fields will scroll down to the next line on the report after 44 characters. This has no effect on the interpretation of the calculation.
