# "UnsignedInteger16"(Compiled Type)

"UnsignedInteger16"

represents an unsigned 16-bit machine integer atomic type specifier.

# Details

• "UnsignedInteger16" can be used in Typed and related constructs to specify a type.

# Properties

• Values held by "UnsignedInteger16" range from 0 to 216-1.

# Conversions

### From Expressions

• Suitably sized Integer expressions can be converted into compiled code elements with the type "UnsignedInteger16".
• ### To Expressions

• "UnsignedInteger16" compiled elements can be converted into Integer expressions.
• ### Arithmetic

• "UnsignedInteger16" compiled elements are automatically promoted to real or complex elements when they are combined in binary arithmetic operations.
• Compiled elements with types smaller than "UnsignedInteger16" are automatically promoted to "UnsignedInteger16" when they are combined in binary arithmetic operations.
• "UnsignedInteger16" compiled elements are automatically promoted to larger integral elements when they are combined in binary arithmetic operations.
• "Integer16" compiled elements are automatically promoted to "UnsignedInteger16" elements when they are combined in binary arithmetic operations.

# Runtime Errors

### Overflow

• "UnsignedInteger16" can give a runtime error if it is used in an operation that overflows.

# Examples

## Basic Examples(3)

"UnsignedInteger16" can be used as an input and output from a CompiledCodeFunction:

An overflow causes an error while running the function. The computation is terminated, a message is issued and the Wolfram Engine is used to compute the result:

The "UnsignedInteger16" argument is automatically promoted when combined with a real number:

When an "UnsignedInteger16" argument is combined with an integer of a smaller storage size, the smaller type is automatically promoted:

The "UnsignedInteger16" argument is automatically promoted when combined with an integer of a larger storage size:

The signed integer of the same storage size is automatically promoted when combined with an "UnsignedInteger16":
