   :members:

.. _VV_DOUBLE_CRC_BITS:

VV_DOUBLE_CRC_BITS constants
-----------------------------------------------------------------------

::

   Number of bits to use in double CRC's 

.. autoattribute:: geosoft.gxapi.VV_DOUBLE_CRC_BITS_EXACT

::

   Exact CRC 

.. autoattribute:: geosoft.gxapi.VV_DOUBLE_CRC_BITS_DEFAULT

::

   Default inaccuracy in double (10 Bits) 

.. autoattribute:: geosoft.gxapi.VV_DOUBLE_CRC_BITS_MAX

::

   Maximum number of inaccuracy bits 

.. _VV_FLOAT_CRC_BITS:

VV_FLOAT_CRC_BITS constants
-----------------------------------------------------------------------

::

   Number of bits to use in float CRC's 

.. autoattribute:: geosoft.gxapi.VV_FLOAT_CRC_BITS_EXACT

::

   Exact CRC 

.. autoattribute:: geosoft.gxapi.VV_FLOAT_CRC_BITS_DEFAULT

::

   Default inaccuracy in floats (7 Bits) 

.. autoattribute:: geosoft.gxapi.VV_FLOAT_CRC_BITS_MAX

::

   Maximum number of inaccuracy bits 

.. _VV_LOG_BASE:

VV_LOG_BASE constants
-----------------------------------------------------------------------

::

   Type of log to use 

.. autoattribute:: geosoft.gxapi.VV_LOG_BASE_10

::

   Base 10 

.. autoattribute:: geosoft.gxapi.VV_LOG_BASE_E

::

   Base e 

.. _VV_LOG_NEGATIVE:

VV_LOG_NEGATIVE constants
-----------------------------------------------------------------------

::

   Ways to handle negatives 

.. autoattribute:: geosoft.gxapi.VV_LOG_NEGATIVE_NO

::

   dummies out value less than the minimum. 

.. autoattribute:: geosoft.gxapi.VV_LOG_NEGATIVE_YES

::

   
   					if the data is in the range +/- minimum,
   					it is left alone.  Otherwise, the data
   					is divided by the minimum, the log is
   					applied, the minimum is added and the
   					sign is reapplied. Use LogLinear_VV function
   					if decades in results are required.
