Unsigned 128-bit integer, from 0 through 340282366920938463463374607431768211455; checked arithmetic.
Signature
Integer arithmetic checks overflow; floating-point arithmetic rounds each operation at its declared precision and rejects nonfinite results. Mixed representations require explicit conversion, which rejects loss of range or precision. Values serialize as decimal strings so JSON hosts retain the exact value.
Methods
Examples
Calculate at a declared precision
Both operands have this dtype; changing the annotation changes its range and precision.
Devices
Use this scene on another device
Show a QR code for your glasses, or send a link to another browser. You can keep working here.
Sharing starts a fresh run of the last compiled code. Your editor draft stays here.
Join a session
Open an invitation link, or paste a link or code from the other device.
Connect your other device
On RayNeo, open Menu → Connect live and scan this code. In another browser, open the invitation link below.
Or enter this code:
Waiting for another device. You can keep working while it connects.
Browsers can edit code; every device can use scene controls. The device that started the session controls playback.
Connection settings
A full invitation link includes its host. With a code alone, both devices need the same live host. Pairing setup
