/**
* This is an example of wrapping a shortcode around the LearnDash [courseinfo] shortcode to control the format.
*
* In the following example we are targeting the courseinto item 'cumulative_percentage'. By default the
* value returned via LearnDash will be a number with 2 decimal places. We want to round the number value
* to the closest whole integer.
*
* For this we wrap the LearnDash shortcode with our own [number_format][/number_format] as in
* [number_format show="cumulative_percentage" decimal_places="1"][courseinfo show="cumulative_percentage"][/number_format]
* We use the same show="" parameter this was we only have one shortcode function instead of one for each of the courseinfo items.
* Also, we have a second optional parameter decimal_places="" this is used to control the number of decimal places to trim to.
* If not provided the default is decimal_places="2".
*
