.Val stands for the number value that is its first parameter. Val specializes in scientific notations and uncertainty notations, and in a measurement value with physical units. It formats the number (with possible unit) according to the Manual of Style and keeps the expression from wrapping across lines.Express a numeral:Express a measurement value with a unit, for example {{val|4|ul=m/s2}}
→ 4 m/s2. The keyboard characters m/s2 are a "unit code" that |u=m/s2
marks up, or that |ul=m/s2
additionally links to its articulation.Because the unit spacing and markup is a style issue, Val provides these for you. There are a large number of unit codes that Val understands and keeps "up to code". A unit code is usually composed of one or more abbreviated unit names and the usual math symbols on the typical keyboard. See {{Val/units}}. Some unit-code flexibility is provided by having four parameters to work the unit-code system: whether to link one or not, (see Overlinking) , and whether to form a ratio or not with a unit code.To bypass the unit code system, if |u=
does not recognize your unit code, it will accept any wikitext and render it as usual.See below for § How to add units to the unit code system. Sometimes a number and unit code is not enough. A prefix or suffix are also available, |p=
and |s=
.See {{val/testcases}} to learn the val parameters by a example. It's comprehensive, and there's over 100 examples.{{val|1234567.1234567}}

(see above).A hidden sort key is added to the output for sorting in sortable tables. The sort key is based on the main value (parameter |1=
) and, if used, the exponent for the power of 10 (parameter |e=
) and/or units (parameters |u=
, |ul=
, |up=
and/or |upl=
). Where necessary, units are converted to base SI units for the purpose of the sort key, which is produced by {{ntsh}}. Several units are covered; see § How to add units for those which are not. To omit the sort key use |sortable=off
