Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted

Usage

This template rounds parameter 1 by parameter 2 decimal places (goes the other way for negative rounding) and includes trailing zeros.

{{rnd|54.376|2}}     gives Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted
{{rnd|54.376|-1}}   gives Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted
{{rnd|68.4273E12|-10}} gives Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted

For example, rounding by 1 gives 1 decimal digit, rounding by 0 gives integers, or rounding by -2 gives the amount in hundreds. Scientific notation is displayed for numbers greater than or equal to 1×109, or less than 1×10−4.

Examples:

  • {{rnd|2.0004|3}} gives Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted
    • whereas {{[[Шаблон:#expr:2.0004 round 3|#expr:2.0004 round 3]]}} gives 2
  • {{rnd|0.000020004|7}} gives Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted
  • {{rnd|0|8}} gives Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted
  • {{rnd|154268|-3}} gives Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted
  • {{rnd|154568|-3}} gives Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted
  • Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted
    • whereas Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted, even though Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted (see m:Help:Format produced by expr)
  • Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted
  • Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted
  • Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted
  • Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted
  • Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted
  • Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted
  • Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted
  • Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted
  • Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted

As with #expr, the total number of significant digits is not more than 14:

  • Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted
  • Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted
  • Lua error: Cannot create process: proc_open(/dev/null): failed to open stream: Operation not permitted

Internal details

The markup-based version of Template:rnd uses three subtemplates:

  • {{rnd/-}} — for trailing zeros
  • {{rnd/e+}} — for scientific notation for numbers greater than or equal to 109 or less than or equal to −109
  • {{rnd/e−}} — for scientific notation for numbers greater than −10−4 and less than 10−4 but not equal to zero

The Lua-based version of {{rnd}} uses Module:Math and always has an expansion depth of 3. However, the markup-based version has an expansion depth of 9–15, which depends on the size of the numbers (integer results use depth 9, decimals use depth 12), where astronomical numbers can hit expansion depth of 15 levels, for {{rnd|56.44e33|-32}} → 5.64 × 1034.
