Limit the number of decimals on a number using the half up rounding algorithm.

If decimals is set to zero, generates integers by always rounding down (e.g. chopping off the trailing decimal suffix).

Examples​

Rounding to two decimals​

Use 2 decimals to drop the remaining decimal places.

{
    "_gen": "constant",
    "x": 10.12345,
    "decimals": 2
}
[
    10.12
]
