Purpose
မႄးထတ်းThis template is used to easily present values in scientific notation, including uncertainty and/or units. It wraps the entire result in a {{nowrap}} block, so that it never gets broken into separate pieces at the end of a line.
Arguments
မႄးထတ်းThere 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 1,234±56.{{val|number|upper uncertainty|lower uncertainty}}- for displaying values with uncertainty like so 1,234+56−78.{{val|number|(significance)}}- for displaying values with significance like so 1,234(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 " × 10e". |
| 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... |
Errors
မႄးထတ်းThere is strict checking on the validity of arguments; any incorrect use will result in an error, which is displayed using {{Formatting error}}.
Format convention
မႄးထတ်း{{Val}} should produce formatting compliant with the U.S. Government Printing Office Style Manual, in rules 12.9e and 12.14, which requires that the decimal separator be a full stop; 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 1,000 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).
Examples
မႄးထတ်း{{Val|1234567890}}→ 1,234,567,890 {{Val|1.23456789}}→ 1.23456789 {{Val|21563.252564425}}→ 21,563.252564425 Uncertainty/significance {{Val|1.234|0.005}}→ 1.234±0.005 {{Val|1.234|+0.005|-0.006}}→ 1.234+0.005−0.006 {{Val|1.234|(5)}}→ 1.234(5) Exponents/units {{Val|1.234|e=5|u=m}}→ 1.234×105 ထႅမ်းပလဵတ်ႉ:Convert/ScientificValue/LoffAonSoff {{Val|1.234|e=5|u=m2}}→ 1.234×105 ထႅမ်းပလဵတ်ႉ:Convert/ScientificValue/LoffAonSoff {{Val|1.234|e=5|ul=m}}→ 1.234×105 m {{Val|1.234|0.056|e=7}}→ 1.234±0.056×107 {{Val|1.23456|+0.00007|-0.00008|e=-9|ul=m/s}}→ 1.23456+0.00007−0.00008×10−9 m/s {{Val|1.234|0.056|e=7|ul=psi}}→ 1.234±0.056×107 psi {{Val|123.4|ul=USgal}}→ 123.4 USgal {{Val|12.34|ul=mpgimp}}→ 12.34 mpgimp Prefix/suffix {{Val|p=Δ |12.34|s=%}}→ Δ 12.34%
Performance impact
မႄးထတ်းFor most uses, in the text of pages, 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.
