`uint32`

Converts values to unsigned 32-bit integers (0 to 4294967295).

Category: Language Fundamentals > Data Types

Syntax

Y = uint32(X)

Converts X to class uint32.

Description

Values are rounded to the nearest integer (halves away from zero) and then saturate: anything above 4294967295 becomes 4294967295, and negative numbers and NaN become 0. No error or warning is raised. For example, uint32(5e9) gives 4294967295.

Arithmetic between uint32 and a double gives a uint32 result, rounded and saturated again, so uint32(7)/uint32(2) is 4. Mixing two different integer classes in one operation is an error. intmax('uint32') gives the largest value.

Input arguments

X: Numeric, logical or char array.

Output arguments

Y: Array of class uint32 with the same size as X.

Example

Rounding and saturation

uint32(5e9)
uint32(7)/uint32(2)
intmax('uint32')

Output

ans = uint32
   4294967295
ans = uint32
   4
ans = uint32
   4294967295
