Custom Numeric FormatsOrigin-Formats
Origin supports custom formatting of numeric worksheet data, text objects, and axis tick labels, using the following options.
 | Two zero control check boxes with the potential to override custom numeric formatting of axis tick labels, have been added to Options (Preference: Options: Axis):
- Zero is '0'
- No Trailing Zero

Other Numeric Formats
| Format
|
Description
|
Example
|
| #n or ##
|
Display an integer to n places, zero padding where necessary. Or use n number of #'s to refer to nth places
|
1 using #2 ⇒ 01
12 using ### ⇒ 012
|
| ##+##
|
Display a number as two or more digits, a "+" separator, then two digits (e.g. surveying stations).
|
12345.67890 using ##+## ⇒ 123+46

|
Display a number as number, a "+" separator, then two digits, plus suffix "M".
|
12345.67890 using #+##M ⇒ 123+46M
|
| -+
|
Combine with other numeric formats (e.g. decimal places, significant digits, etc.) to display a "long minus" for negative and/or a "plus" symbol for positive numbers. Note that the "-" and "+" symbols may be used together (e.g. "-+") or separately (e.g. "-").
In the following example, we prefix "+" which forces display of a "+" sign for positive numbers, while specifying two decimal places.
|
71.4637865176 using +.2 ⇒ +71.46 km
|
Fractions
| Format
|
Description
|
Example
|
| # ##/##
|
Display a number as proper fraction. The first # indicates the integer part of the mixed number and the rest part after space indicates the remainder. In the reminder part, a forward slash / separates numerator and denominator. The numbers of # in both can be varied, indicating the number of digits of remainder. For example, # #/# displays remainder with up to 1 digit, # ##/## displays remainder with up to 2 digits, and so on.
|
71.4637865 using # ##/## ⇒ 71 32/69
|
| # #/n
|
Round and display a number as a fraction with specified n as denominator. The numerator and denominator are separated by a forward slash /. The number of digits of numerator is adjusted accordingly.
|
71.4637865 using # #/8 ⇒ 71 4/8
|
Percentages
| Format
|
Description
|
Example
|
| #%
|
Display a number as a percentage.
|
0.714637865176373 using #% ⇒ 71%
|
| #[.##]%
|
Display a number as a percentage with decimal place, truncating trailing zeros. while #.#% displays percentage as 1 decimal place and #.##% displays 2 decimal places.
|
0.021 using #.##% ⇒ 2.1%
|
| #[.00]%
|
Display a number as percentage of 100 followed by the percent sign "%". #% displays percentage as integer, while #.0% displays percentage as 1 decimal place and #.00% displays 2 decimal places. Note that the square brackets in the format indicate an optional argument; they are not entered in your expression.
|
0.021 using #.00% ⇒ 2.10%
|
| Note: From Origin 2024, percentage supports up to 12 decimal places. For example, you can specify #.####% to display 0.714637865176373 as 71.4638%.
|
pi
The quantity pi (π) is treated specially in the Origin worksheet. Once you have set the Column Properties Custom Display list to one of the pi options, you can enter multipliers directly (e.g. 1,2,3, etc.) and Origin will convert the display to pi units (e.g. π, 2π, 3π, etc.).
| Format
|
Description
|
Example
|
| * "pi"
|
Display a number as a decimal, followed by the symbol π.
Note that converting this value back to a simple Text & Numeric or Numeric format, displays a scaled decimal quantity (e.g. "2π" becomes "6.28319...").
|
1 using * "pi" ⇒ 0.31831π
|
| #/4 "pi"
|
Display a number as π divided by "4", with rounding.
Note: If you click into the cell containing "3π/4", the cell displays the a decimal in π units ("0.75") in edit mode; but converting this column back to a simple Text & Numeric or Numeric format displays a scaled decimal quantity ("2.35619...").
|
1 using #/4 "pi" ⇒ π/4
|
| #/# "pi"
|
Display a number as a fraction of π. See the note in the cell above.
|
1 using #/# "pi" ⇒ π/3
|
Other Prefix and Suffix Units
| Format
|
Description
|
Example
|
| "$"*
|
Display a number with a dollar sign ($) prefixed.
|
71.4637865176 using "$".2 ⇒ $71.46
|
| *n "km"
|
Display a number to n significant digits, with the "km" (kilometers) suffixed.
|
71.4637865176 using *3 "km" ⇒ 71.5 km
|
 | Origin's syntax for custom formats can sometimes be generalized. For instance, to display a number as dollars + cents (e.g. $2.50), you combine a "$" prefix with the ".n" notation from the first table to limit decimal display to 2 (i.e. "$.2").
|
Geographic Coordinate Notation
| Format
|
Description
|
Example
|
| DMS
|
Display a number in Degrees° Minutes' Seconds", where 1 degree = 60 minutes, and 1 minute = 60 seconds.

|
| DMF
|
Display a number in Degrees Minutes Seconds, without unit symbols.
|
42.3251 using DMF ⇒ 42 19 30
|
D MDn EW (longitude)
D MDn NS (latitude)
|

|
42.3251 using D MD3 NS ⇒ 42° 19.506 N
-72.6412 using D MD3 EW ⇒ 72° 38.472 W
-72.6412 using D MD3 ⇒ -72° 38.472
|
D MDn EWB (longitude)
D MDn NSB (latitude)
|
Display a number in Degrees and Decimal Minutes. Parameter n specifies decimal places. Letter "B" ("before") specifies that positive values should have "E" or "N" prefixed, negative values will have "W" or "S" prefixed. To preserve negative values do not append "EWB" or "NSB".
|
42.3251 using D MD3 NSB ⇒ N 42° 19.506
-72.6412 using D MD3 EWB ⇒ W 72° 38.472
-72.6412 using D MD3 ⇒ -72° 38.472
|
Dn EW (longitude)
Dn NS(latitude)
|
Display a number in Decimal Degrees. Parameter n specifies decimal places. Positive values will have "E" or "N" appended, Negative values will have "W" or "S" appended.
|

-72.6412 using D3 EW ⇒ 72.641° W
Note: To display simply "42.3251" or "-72.6412", set
Format = Numeric
Display = Decimal:1000.
