name: "ceil"
description: >
Rounding to the ceiling of the value `x`.

- value: fp32

description: >
Rounding to the floor of the value `x`.
impls:
- args:
- value: fp32

return: fp32

name: "round"
description: >
Rounding the value `x` to `s` decimal places.
impls:
- args:
- value: i8
name: "x"
description: >
Numerical expression to be rounded.
- value: i32
name: "s"
description: >
Number of decimal places to be rounded to.
When `s` is a positive number, nothing will happen
since `x` is an integer value.
When `s` is a negative number, the rounding is
performed to the nearest multiple of `10^(-s)`.

When a boundary is computed to lie somewhere between two values,
and this value cannot be exactly represented, this specifies how
to round it.
- TIE_TO_EVEN: round to nearest value; if exactly halfway, tie
to the even option.
- TIE_AWAY_FROM_ZERO: round to nearest value; if exactly
halfway, tie away from zero.
- TRUNCATE: always round toward zero.
- CEILING: always round toward positive infinity.
- FLOOR: always round toward negative infinity.
- AWAY_FROM_ZERO: round negative values with FLOOR rule, round positive values with CEILING rule
- TIE_DOWN: round ties with FLOOR rule
- TIE_UP: round ties with CEILING rule
- TIE_TOWARDS_ZERO: round ties with TRUNCATE rule
- TIE_TO_ODD: round to nearest value; if exactly halfway, tie
to the odd option.
