## UINT32 Convert to Unsigned 32-bit Integer

Section: Type Conversion Functions

### Usage

Converts the argument to an unsigned 32-bit Integer. The syntax for its use is

       y = uint32(x)

where `x` is an `n`-dimensional numerical array. Conversion follows the general C rules (e.g., if `x` is outside the normal range for an unsigned 32-bit integer of `[0,4294967295]`, the least significant 32 bits of `x` are used after conversion to an integer). Note that both `NaN` and `Inf` both map to 0.

### Example

The following piece of code demonstrates several uses of `uint32`.

    --> uint32(200)

    ans =

     200

In the next example, an integer outside the range of the type is passed in. The result is the 32 least significant bits of the argument.

    --> uint32(40e9)

    ans =

     1345294336

In the next example, a negative integer is passed in. The result is the 32 least significant bits of the argument, \emph{after} taking the 2's complement.

    --> uint32(-100)

    ans =

     4294967196

In the next example, a positive double precision argument is passed in. The result is the unsigned integer that is closest to the argument.

    --> uint32(pi)

    ans =

     3

In the next example, a complex argument is passed in. The result is the unsigned integer that is closest to the real part of the argument.

    --> uint32(5+2*i)

    ans =

     5

In the next example, a string argument is passed in. The string argument is converted into an integer array corresponding to the ASCII values of each character.

    --> uint32('helo')

    ans =

     104 101 108 111

In the last example, a cell-array is passed in. For cell-arrays and structure arrays, the result is an error.

    --> uint32({4})
    Error: Cannot convert cell-arrays to any other type.
