rnd|54.376|2
}} gives 54,38rnd|54.376|-1
}} gives 50rnd|68.4273E12|-10
}} gives 6,843×1013For 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

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.
