To define a non-default format of results, after the appropriate results symbol, type:
- A letter to define the format
- A number to define the precision of the results
See the valid letters to define the format in the table below:
The number after the letter indicates the precision of the required results, and should be in the range 15 to -15.
- A positive number indicates the required number of decimal places or significant figures.
- A negative number indicates that the result is to be rounded to the nearest value, which depends on the magnitude of the negative number (-1 signifies 10, -2 signifies 100, -3 signifies 1000, and so on).
General and scientific formats are identical for numbers ≥107 and ≥10-7. Otherwise, the general format is similar to the fixed format, except that any trailing zeros after the decimal point are removed.
The engineering format gives a number between 1 and 999 × 10?, where ? is a multiple of 3 (3, 6, 9, -3 and so on).
The following examples show some typical formats:
- ?E3 - final results field, engineering format, 3 significant figures
- #2 - intermediate results field, default format, 2 decimal places / significant figures
- ?S-3 - final results field, scientific format, rounded to the nearest 1000
