Know the limits

Results are binary floating-point approximations of π multiples.

The function above is the implementation used by the lab. The lab validates JSON types and caps size before execution; include equivalent validation when accepting untrusted input in your application.

Source & maintenance

Original implementation kept; finite-number validation and floating-point note. Original MDX retained as inert source evidence.

Keep exploring

Check if a rectangle contains another one — Compare corners: a contains b when b’s corners sit inside or on a’s edges.
Check if a rectangle overlaps another one — Two rectangles overlap when they overlap on both axes.
Calculate the angle of a line defined by two points — Use Math.atan2 for the angle from the x axis, in radians or degrees.
