Data types

WData format supports three data types:

  • real
  • complex
  • vectors

Each of which can be saved with single (float in C notation) or double (double in C notation) precision. See example-write.c how one can create a variable:

    wdata_variable vdensity_a = {"density_a", "real8", "none", "wdat"};

Here, real8 denotes the double-precision (default), if one wants to save a space and store variables in single-precision one should change it to real4.

If there is a complex number one wants to store then in order to add:

    wdata_variable vdelta = {"delta", "complex16", "none", "wdat"};

here, complex16 denotes the double-precision (default), if one wants to save a space and store variable in single-precision one should change it to complex8.

Similar syntax is used in vectors variable:

    wdata_variable vcurrent_a = {"current_a", "vector8", "none", "wdat"};

here each element of a vector (number of elements depends on the datadim) is a double-precision, real8 number.
