NumericArray[array,type]

creates a numeric array of the specified type.

NumericArray[array,type,method]

uses method to convert numbers into type.

• NumericArray provides the most compact representation of array to reduce memory usage and enhance speed of execution.
• The input array can be a full list of any depth containing machine‐sized integers and machine‐sized approximate real and complex numbers.
• Possible settings for type include:
• NumericArray[array,type] clips values to the range supported by type and rounds reals to integers, if necessary.
• Other conversion method settings include:
• "Check" checks values to be compatible with type "Coerce" coerces to type "Round" rounds reals to integers "ClipAndCheck" clips to the range and checks for compatible type "ClipAndCoerce" clips to the range and coerces to type "ClipAndRound" clips to the range and rounds reals to integers
• For complex numbers, the method is applied separately to real and imaginary parts.
• NumericArray is treated as a raw object by functions like AtomQ and for purposes of pattern matching.
• Normal[NumericArray[…]] yields the list of values in the numeric array.
• Functions such as Length, Equal and First work with NumericArray objects.
• Functions such as Part, Take and Drop can be used to take or drop parts of a NumericArray object.
• Functions such as ListPlot, ArrayPlot and BarChart can visualize a NumericArray object.

Create a vector of byte size integers:

Convert a matrix of reals to a numeric array:

Convert back to a regular list:

Create an 8-bit unsigned integer numeric array:

For a larger integer, use a larger integer type:

Clip large values into a smaller integer type:

Real numbers can be rounded when converted into an integer type:

Create a 32-bit real numeric array:

Coerce exact numbers into reals:

Create a complex numeric array:

Coerce exact real and imaginary parts of a complex number into reals:

Convert an "Integer8" array to "Real32":

If numbers cannot be represented in the new type, specify a conversion method:

Flatten a numeric array:

Normal converts a numeric array to a List:

Apply Join to numeric array objects:

Use Part to take a part of a numeric array:

Use Take to take a part of a numeric array:

Apply Drop to elements of a numeric array:

Some conversion methods may not give numbers suitable for the new type:

Use a conversion that yields numbers supported by the new type:

The default conversion method will fail when the input array contains numbers that are out of range for the specified type.

Try to store in an "Integer8" numeric array:

Use the "ClipAndCoerce" method to automatically clip to the smallest "Integer8":
