टेम्पलेट:Round

टेम्पलेट बिबरनलेख[देखीं] [संपादन करीं] [इतिहास देखीं] [रिफ्रेश करीं]

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 4significant digits,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 "123.4560"[1]
• "{{round|123.456|3}}"gives "123.456"[2]
• "{{round|123.456|2}}"gives "123.46"[3]
• "{{round|123.456|1}}"gives "123.5"[4]
• "{{round|123.456|0}}"gives "123"[5]
• "{{round|123.456|-1}}"gives "120"[6]
• "{{round|123.456|-2}}"gives "100"[7]
• "{{round|123.456|-3}}"gives "0"[8]

• "{{round|123456.789}}"→ "123,457"[9]
• "{{round|12345.6789}}"→ "12,346"[10]
• "{{round|1234.56789}}"→ "1,235"[11]
• "{{round|123.456789}}"→ "123"[12]
• "{{round|12.3456789}}"→ "12"[13]
• "{{round|1.23456789}}"→ "1"[14]
• "{{round|.123456789}}"→ "0"[15]
• "{{round|.0123456789}}"→ "0"[16]
• "{{round|.00123456789}}"→ "0"[17]

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

• "{{round|123.04}}"→ "123"[18]
• "{{round|12.304}}"→ "12"[19]
• "{{round|1.2304}}"→ "1"[20]

While this is a limitation of the template (normally there would be trailing zeros to show theprecision), 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}}"→ "1,230"[21]
