math-round	Math.round	math	namespace-method	Math.round	Math.round(x) -> int	Round a fixed value to the nearest whole int.	7	Math	round

Takes a fixed value and returns the nearest int, with halves rounding up: Math.round(2.5) is 3 and Math.round(2.4) is 2. Choose it over Math.floor when you want the closest whole value rather than always the lower one — snapping a smoothly-moving sprite to a pixel, or reporting a fractional total as a clean number.

Parameters:

• x — the fixed value to round to nearest

program SnapToPixel {
  let smooth_x: fixed = 10.5

  handler Draw phase Render {
    let px = Math.round(smooth_x)   # 11
  }
}
