UINT16 Convert to Unsigned 16-bit Integer

Section: Type Conversion Functions

Usage

Converts the argument to an unsigned 16-bit Integer. The syntax for its use is 
   y = uint16(x)

where x is an n-dimensional numerical array. Conversion follows saturation rules (e.g., if x is outside the normal range for an unsigned 16-bit integer of [0,65535], it is truncated to that range. Note that both NaN and Inf both map to 0.

Example

The following piece of code demonstrates several uses of uint16. 
--> uint16(200)

ans = 
 200

In the next example, an integer outside the range of the type is passed in. The result is truncated to the maximum value of the data type. 

--> uint16(99400)

ans = 
 65535

In the next example, a negative integer is passed in. The result is truncated to zero. 

--> uint16(-100)

ans = 
 0

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

--> uint16(pi)

ans = 
 3

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

--> uint16(5+2*i)

ans = 
   5.0000 +  2.0000i

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. 

--> uint16('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. 

--> uint16({4})
