Signature

function fromUIAmount(uint256 uiAmount) external view returns (uint256);

Field	Value
Selector	0x65cd9b3c
Canonical signature	fromUIAmount(uint256)

Description

Converts uiAmount to its raw token representation at the effective multiplier.

Part of the ERC-8056 optional Conversion extension (IScaledUIAmountConversion, interface ID 0x57854fc3). The inverse operation is toUIAmount(rawAmount).

Integer division truncates toward zero, so the round-trip fromUIAmount(toUIAmount(x)) may return a value less than x by up to 1 wei when the multiplier does not evenly divide the amount.

Parameters

Name	Type	Description
uiAmount	uint256	UI (scaled) amount to convert back to raw.

Returns

Name	Type	Description
(unnamed)	uint256	Raw token amount at the effective multiplier: uiAmount * WAD_PRECISION / multiplier.
