The digit(s) after this indicate how many digits to use for the exponent.

Both use E+ to indicate exponent notation. The current scientific notation in both Excel and OOo Calc is the same except for this point. The Excel format string for engineering notation is similar to the scientific notation, except that it starts with 3 hashes (#). 0.00+E0 would force a 2 decimal fraction if needed or not. In all numeric notations the format string could indicate how many digits to display for the fraction portion of the number.

153,100 in Binary Prefix Notation would become 149.51Ki.Įxample of how other software handle these formats.Įngineering Notation in Microsoft Excel 2003Įach number format requires a format string to indicate not just what type of format to use, but also details as per how many decimals to display. As a convention similar symbols to SI is used, but with an 'i' suffix to distinguish then. Rather the closest matching power of 2 is used. Binary Prefix Notation works in much a similar way, but is not calculated using 10 as a multiple (as with Scientific). This is very similar to SI, but is intended for use when referring to sizes of data storage. Note that SI explicitely forbid 153.1k with the prefix 'k' packed to the number, and require a space between Binary Prefix Notation Similar to Engineering Notation the exponent also runs in multiples of 3 (usually), but the difference is that instead of showing the E+/- notation a symbol is given for each exponent. This is what's known as SI Prefix notation. Thus a number such as 153,100 becomes 153.1E+3 in Engineering notation instead of 1.531E+5 in scientific. The difference is that the exponent is only shown in multiples of 3.

This type of notation is an offshoot of Scientific Notation. The following is a short description of all the number formats to be discussed here. 2.1 Engineering Notation in Microsoft Excel 2003.
