# uaddCarry

## Name

uaddCarry — add unsigned integers and generate carry

## Declaration

`genUType uaddCarry(` | genUType x,
| genUType y,
| out genUType carry`)`;

## Parameters

`x`

  Specifies the first vector to be used in the summation operation.

`y`

  Specifies the second vector to be used in the summation operation.

`carry`

  Specifies the variable to receive the carry output of the sum.

## Description

`uaddCarry` adds two 32-bit unsigned integer variables (scalars or vectors) and generates a 32-bit unsigned integer result, along with a carry output. The result is the sum of `x` and `y` modulo 2 32. The value `carry` is set to 0 if the sum is less than 2 32 and to 1 otherwise.
