Conversion of input vector elements of type T1 into vector of elements of type T0 with saturation.

The following conversions are supported:

  • T0 and T1 is the same floating-point type (including half). In this case the result in the i'th lane is:

    • 0 if src[i] is less than 0
    • 1 if src[i] is greater than 1
    • src[i] otherwise

    I.e. it is always a value in the range [-1, 1].

  • T0 is an integral type, T1 is any valid element type. In this case the (per-element) result is the closest representable value. For example:
    • Too big (exceeding representable range of T0) positive integral or floating-point value src[i] of type T1 converted to T0 will result in std:numeric_limits<T0>::max().
    • Too big negative value will be converted to std:numeric_limits<T0>::min().
    • Negative integer or floating point value converted to unsigned T1 will yield 0.
      Template Parameters
      T0Element type of the returned vector.
      T1Element type of the input vector.
      SZSize of the input and returned vector.
      Parameters
      srcThe input vector.
      Returns
      Vector of src elements converted to T0 with saturation.
