Template:Val/doc

Purpose

Set of templates that can be used to easily present values in scientific notation, including uncertainty. They have the same look and feel and wrap the entire result in a"nowrap" block, so it never gets broken in seperate pieces at the end of a line.

Arguments

There 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).

u The units for the number (optional).

Values (arguments 1-3) are run through {{delimitnum}} for readability. This may mess them up if the last few digits are on the right hand side of the decimal dot and they are zero. This is a known issue.
Units are replaced by a more esthetically pleasing HTML representation and get a link, if they are in the list found in {{ScientificValue/units}} or if they are supported by {{convert}}. A good example is "m/s", which gets translated to "m·s^-1".

Errors

There 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 Category:Pages with incorrect formatting templates use.

Test

To see if this template is working correctly (for instance after you've made a change to the code), have a look at: {{Val/test}}. It contains a number of tests.
