সাঁচ:Worldpop

 {{ #expr: {{worldpop-base}} + {{worldpop-daily-inc}} * {{Age in days|2012|7|1}} round -2 }}

• Looks better with commas:
• Present value of {{worldpop-base}} is 7,02,33,24,899
• Present value of {{worldpop-daily-inc}} is 2,11,203.375

• Automatically updates ONCE per day at 00:00 UTC (possibly offset during daylight savings)
• Formatted to nearest 100 to reduce likelihood of display in scientific notation, and also to avoid false precision

Regarding rounding

• if rounded to nearest 100-thousand, will often display in scientific notation
• if round ends in 5 zeroes, there is an intermittent sci notation problem
• This CAN happen even if the number is rounded to 0 places - IF the number ends in 5 zeroes
• results are inconsistent, seemingly dependent on which server renders the numbers
