evm_clamp

Constrains x to the inclusive range [lo, hi] when lo <= hi. For compatibility, reversed bounds lo > hi return lo; reversed bounds do not describe a valid interval. NULL input propagates to NULL.

Example

Runs locally

SELECT evm_clamp(7::UINT256, 10::UINT256, 5::UINT256)::VARCHAR AS result;
-- => [{"result":"10"}]

API reference

evm_clamp(UINT256, UINT256, UINT256) #

Returns max(lo, min(hi, x)) for valid bounds; current compatibility behavior returns lo for lo > hi.
