الگو:Round/توضیحات

This templates rounds parameter 1 to the number of digits after the point optionally given as parameter 2. If parameter 2 is negative, rounding is to a multiple of 10. If parameter 2 is undefined, numbers with 4 digits before the point are rounded to integers, numbers with 3 digits before the point are rounded to 1 digit after the point, numbers with 2 digits before the point are rounded to 2 digits after the point, and numbers with 1 digit before the point or none are rounded to 3 digits after the point.

In other words, if parameter 2 is undefined, rounding is to 4 ارقام قابل توجه, except that it is not cruder than rounding to an integer and not finer than rounding to three digits after the decimal point.

Examples:

• "{{round|123.456|4}}" gives "۱۲۳٫۴۵۶۰" [۱]
• "{{round|123.456|3}}" gives "۱۲۳٫۴۵۶" [۲]
• "{{round|123.456|2}}" gives "۱۲۳٫۴۶" [۳]
• "{{round|123.456|1}}" gives "۱۲۳٫۵" [۴]
• "{{round|123.456|0}}" gives "۱۲۳" [۵]
• "{{round|123.456|-1}}" gives "۱۲۰" [۶]
• "{{round|123.456|-2}}" gives "۱۰۰" [۷]
• "{{round|123.456|-3}}" gives "۰" [۸]

• "{{round|123456.789}}" → "۱۲۰۰۰۰" [۹]
• "{{round|12345.6789}}" → "۱۲۰۰۰" [۱۰]
• "{{round|1234.56789}}" → "۱۲۰۰" [۱۱]
• "{{round|123.456789}}" → "۱۲۰" [۱۲]
• "{{round|12.3456789}}" → "۱۲" [۱۳]
• "{{round|1.23456789}}" → "۱٫۲" [۱۴]
• "{{round|.123456789}}" → "۰٫۱۲" [۱۵]
• "{{round|.0123456789}}" → "۰٫۰۱۲" [۱۶]
• "{{round|.00123456789}}" → "۰٫۰۰۱۲" [۱۷]

Note that trailing zeros are not shown, so rounding can seem cruder than has actually been applied:

• "{{round|123.04}}" → "۱۲۰" [۱۸]
• "{{round|12.304}}" → "۱۲" [۱۹]
• "{{round|1.2304}}" → "۱٫۲" [۲۰]

While this is a limitation of the template (normally there would be trailing zeros to show the ارقام قابل توجه), there is also the general problem that if a number is an integer with trailing zeros, then the precision is not clear:

• "{{round|1230.4}}" → "۱۲۰۰" [۲۱]

• {{roundup}}
• {{rounddown}}
• {{decimals}} – acts like rounding but displays trailing zeros after the decimal point
• {{precision}} – handles rounding of large numbers, too, like "349,030,293" → "349,030,000", "349,000,000", or "350,000,000"
