Sourcery VSIPL++ defines default types for scalar floating-point and integer data, in both real and complex forms:

typedef float scalar_f;
typedef int scalar_i;
typedef std::complex<scalar_f> cscalar_f;
typedef std::complex<scalar_i> cscalar_i;

Sourcery VSIPL++ also supports double-precision scalar and complex data types.

In addition, Sourcery VSIPL++ defines a number of integer types for indices, strides, and other related values.
