Calling Sequence
~~~~~~~~~~~~~~~~


::

    y=int8(X)
    y=int16(X)
    y=int32(X)
    y=uint8(X)
    y=uint16(X)
    y=uint32(X)




Arguments
~~~~~~~~~

:X matrix of floats or integers
: :y matrix of integers coded on one, two or four bytes.
:



Description
~~~~~~~~~~~

converts and stores data two one, two or four bytes integers. These
data types are specialy useful to store big objects such as images,
long signals,...

:y=int8(X) return numbers in the range [-128,127]
: :y=uint8(X) return numbers in the range [0,255]
: :y=int16(X) return numbers in the range [-32768,32767]
: :y=uint16(X) return numbers in the range [0, 65535]
: :y=int32(X) return numbers in the range [-2147483648,2147483647]
: :y=uint32(X) return numbers in the range [0, 4294967295]
:



Examples
~~~~~~~~


::

    `int8`_([1 -120 127 312])
    `uint8`_([1 -120 127 312])
    
    x=`int32`_(-200:100:400)
    `int8`_(x)
