Template:Rndgaps
Usage
[eedit soorce]Like {{rnd}}, this template rounds {{{1}}} to {{{2}}} decimal places (goes the other way for negatives) and includes trailing zeros. Also like {{rnd}}, scientific notation is used for numbers whose absolute value is greater than or equal to 1×109, or less than 1×10−4. It differs from {{rnd}} in that it uses thin gaps to delimit numbers like {{val}} (see also {{gaps}}).
Examples:
{{rndgaps|2.0004|3}}→ 2.000{{rndgaps|0.000020004|7}}→ 2.00×10−5{{rndgaps|0|8}}→ 0.00000000{{rndgaps|154268|-3}}→ 154000{{rndgaps|1200004|-1}}→ 1200000{{rndgaps|1300004|-1}}→ 1300000{{rndgaps|4.1e6|9}}→ 4099999.9990000{{rndgaps|4.1e6|10}}→ 4099999.9990000{{rndgaps|1542689271|-7}}→ 1.54×109{{rndgaps|1542689271|2}}→ 1.54268927100×109{{rndgaps|7e9|-9}}→ 7×109{{rndgaps|-123|1}}→ −123.0{{rndgaps|-1200007|-2}}→ −1200000{{rndgaps|-1234567899|-7}}→ −1.23×109
As with #expr, the total number of significant digits is not more than 14:
{{rndgaps|1234567890.123456789|10}}→ 1.2345678901235×109{{rndgaps|123456789.0123456789|10}}→ 123456789.01235{{rndgaps|.0001234567890123456789|20}}→ 0.00012345678901235
Internal details
[eedit soorce]The template uses the following.
- {{val/delimitnum/fraction}} — for trailing zeros
- {{rndgaps/e+}} — for scientific notation for numbers greater than or equal to 109 or less than or equal to −109
- {{rndgaps/e−}} — for scientific notation for numbers greater than −10−4 and less than 10−4 but not equal to zero
