Where do your exchange rates come from?

Straight from central banks — the European Central Bank, the US Federal Reserve, the Bank of England, the Bank of Canada and the State Bank of Pakistan. Each currency is served by the authority for it, and every rate carries its source and as-of date so you can attribute it.

How often are the FX rates updated?

On each source's own publishing schedule — most central banks publish once per business day. A rate past its expected window is marked stale rather than silently served, and an unpublished currency is absent instead of guessed.

How do you avoid floating-point errors in currency conversion?

All conversion runs in bcmath at scale 12, with amounts passed as strings end to end. A float cannot hold money precisely, so we never use one in the money path — a design rule the test suite enforces.

Live FX rates — LocaleSense

Rates come straight from the ECB, the US Federal Reserve, the State Bank of Pakistan, the Bank of England and the Bank of Canada. Public data, no licence, and a stronger claim than any competitor: sourced from central banks, with staleness reported rather than hidden.

Why it works_

Convert money at a rate you can name

Central-bank provenance

Each currency is served by the bank that is the authority for it; every rate carries its source and as-of date.

Arbitrary precision

Conversions run in bcmath at scale 12 — amounts are strings, never floats, because a float cannot hold money.

Staleness, not silence

A source past its window is marked stale; an unpublished currency is absent, never guessed.
