تخدام
بدلThis template is used to easily present values in كتابة علمية, including uncertainty and/or units, as prescribed by Wikipedia's Manual of Style. It wraps the entire result in a {{بدون لف}} block, so that it never gets broken into separate pieces at the end of a line. (See ويكيپيديا:دليل الأسلوب for more information on the usage of non-breaking spaces.)
Arguments
بدلThere are four ways this template can be used:
{{val|number}}- for displaying values without uncertainty/significance.{{val|number|uncertainty}}- for displaying values with uncertainty like so 1234±56.{{val|number|upper uncertainty|lower uncertainty}}- for displaying values with uncertainty like so 1234+56
−78.{{val|number|(significance)}}- for displaying values with significance like so 1234(56).
They all take roughly the same arguments
| 1 | The value (must be a valid number) |
| 2 | The (upper limit of) uncertainty (must be a valid number) or significance (must be a valid number in parenthesis) |
| 3 | The lower limit of uncertainty (must be a valid negative number) |
| e | The exponent for the power of 10 (optional). This will show up in the result as " × 10موضيل:Su".
|
| u / ul | The units for the number (optional, with/without a link to the page about the unit respectively). |
| up / upl | The units per for the units (optional, requires u to be specified, with/without a link to the page about the unit respectively).
|
| p | A prefix for the value (such as ∆, ⌀, etc.; optional). |
| s | A suffix for the value (such as %, optional).
|
| end | Appends something after the main value. For example, {{val|123.24|end=...}} gives 123.24... |
| errend | Appends something after the uncertainty. For example, {{val|123.23|end=...|2.34|errend=...}} gives 123.23...±2.34... |
| +errend & -errend | Appends something after the positive/negative uncertainties. For example, {{val|123.23|end=...|+2.34|+errend=...|-1.23|-errend=...}} gives 123.23...+2.34... −1.23... |
| nocategory | If set to any value, errors in the use of this template will not cause the page to be added to the صفحات تستخدم قوالب تحتوي على تنسيق غير صحيح category. This is useful for documentation and test pages that do not need to be fixed. |
See {{val/test}} for a list of examples of the correct output of {{val}} and the errors it may return when incorrectly used.
Errors
بدلThere is strict checking on the validity of arguments; any incorrect use will result in an error, which is displayed using {{FormattingError}}. Pages that contain incorrect use of this template will show up on تصنيف:صفحات تستخدم قوالب تحتوي على تنسيق غير صحيح.
Format convention
بدلAs mentioned before, {{val}} should produce formatting compliant with Wikipedia's Manual of Style. It currently produces formatting compliant with the U.S. Government Printing Office Style Manual, in rules 12.9e and 12.14, which requires that the فاصل عشري be a نقطة النهاية؛ i.e. “decimal point” (.), requires comma-delimiting to the left of the decimal point for numbers with four or more digits to the left (values of 1000 or more), and also requires space-delimiting to the right of the decimal point for numbers containing five or more digits to the right (e.g., 0.12345 and 5.12345 and 125.12345).
Note that if {{val}} is used on numbers simultaneously comprising four or more digits to the left of the decimal point and five or more digits to the right, the resultant expression will delimited with commas left and spaces (actually non-selectable, non-breaking, narrow gaps) right (see below).

Performance impact
بدلFor most uses, in the text of articles, Template:Val will not restrict performance, but when used inside the wikitext markup of large templates, there are some restrictions. When displaying integer amounts, Template:Val has an internal expansion depth of 15 levels, but for numbers with decimal portions, it uses 22 levels, or more.
