This is the /data subpage for {{t|physconst}}. It stores all of the values used by the main template.

==वापर==
This subpage uses two switch statements to determine the data sent back to the main template. Use the template below for ease of adding a new constant.

<pre>
     | name =  {{#switch: {{{2}}}
                | symbol = symbol
                | val = significand of physical constant value
                | un1 = standard uncertainty (with leading zeroes)
                | unc = EITHER (standard uncertainty digits; concise form) OR blank if exact
                | round = digits after decimal for default rounding; see below
                | exp = exponent of value
                | runc = significand of relative standard uncertainty
                | rexp = exponent of relative standard uncertainty
                | unit = unit
                | ref = reference footnote (in <ref>...</ref> tags)
</pre>

==Rounding==
{{t|Physconst}} can auto-round a value to the most digits such that the standard uncertainty is no more than 0.5 units in the last place. In other words:
:<math> \text{val}_{round} \pm \text{un1} > \text{val} \mp (0.5 * \text{un1})</math>
This can be seen visually below. A correctly-rounded value will show green for the first two columns and red for the third. If this is not the case, the auto-round value will need to be adjusted. 

'''Please note''' that <code>h</code> is accurate, but shows all three columns green due to the number of 0s in the value.
