2D & 3D point distance: exact radicals
Calculate 2D or 3D Euclidean, Manhattan and Chebyshev distances, exact simplified radicals and signed coordinate differences locally.
About this 2d & 3d point distance: exact radicals
Calculate 2D or 3D Euclidean, Manhattan and Chebyshev distances, exact simplified radicals and signed coordinate differences locally Computes exact algebraic and numerical metrics directly in your browser using IEEE 754 precision without round-trip latency.
Formula & calculation mechanics
Select 2D or 3D, enter A and B in the same coordinate unit, then calculate. Changing input clears old results; switching dimensions preserves coordinate fields.
Worked numerical calculation
Scenario: A=(0,0), B=(5,5): Δ=(5,5); L2=√50=5√2≈7.07106781187, L1=10, L∞=5.
Sample input:
Processing: Δ = B − A; L2 = √(ΣΔ²), L1 = Σ|Δ|, L∞ = max|Δ|. Exact radicals use integer arithmetic on thousandths; decimal distance is rounded to 12 significant digits.
Illustrative output:
Domain range & precision boundaries
Operational constraints and validation boundaries: New form: each coordinate −1000 to 1000, decimal point and up to 3 fractional digits; at most 16 characters, no exponent or whitespace. Exact arithmetic stays below 2⁵³. Same coordinate unit throughout; no geographic or travel-distance interpretation. Legacy JSON retains its original wider vector behavior.

Frequently asked questions
Exact Euclidean distance+
Operational requirements for "Exact Euclidean distance" are verified in local memory during execution of 2D & 3D point distance: exact radicals.
How does Point Distance Calculator (Euclidean & Manhattan) configure dimensions?+
Diagrams translate A to the origin and share a scale within each triangle. XY is a planar projection; the second 3D triangle uses XY distance and signed Δz. Degenerate triangles collapse to a line or point.
