octave: Single Precision Data Types

 
 4.3 Single Precision Data Types
 ===============================
 
 Octave includes support for single precision data types, and most of the
 functions in Octave accept single precision values and return single
 precision answers.  A single precision variable is created with the
 ‘single’ function.
 
  -- : single (X)
      Convert X to single precision type.
 
      See also: double XREFdouble.
 
    for example:
 
      sngl = single (rand (2, 2))
           ⇒ sngl =
              0.37569   0.92982
              0.11962   0.50876
      class (sngl)
          ⇒ single
 
    Many functions can also return single precision values directly.  For
 example
 
      ones (2, 2, "single")
      zeros (2, 2, "single")
      eye (2, 2,  "single")
      rand (2, 2, "single")
      NaN (2, 2, "single")
      NA (2, 2, "single")
      Inf (2, 2, "single")
 
 will all return single precision matrices.
