//  MACRO DEFINITIONS
//  Macro definitions for VML mode and VML error status.
//
//  VML mode controls VML function accuracy, floating-point settings (rounding
//  mode and precision) and VML error handling options. Default VML mode is
//  VML_HA | VML_ERRMODE_DEFAULT | VML_FTZDAZ_CURRENT,
//  i.e. VML high accuracy functions are called,
//  current floating-point precision and the rounding mode is used,
//  current MXCSR settings are left unchanged.
//
//  Error status macros are used for error classification.
//--
*/

/*
//  VML FUNCTION ACCURACY CONTROL
//  VML_HA - when VML_HA is set, high accuracy VML functions are called
//  VML_LA - when VML_LA is set, low accuracy VML functions are called
//  VML_EP - when VML_EP is set, enhanced performance VML functions are called
//
//  NOTE: VML_HA, VML_LA and VML_EP must not be used in combination

//  SETTING OPTIMAL FLOATING-POINT PRECISION AND ROUNDING MODE
//  Definitions below are to set optimal floating-point control word
//  (precision and rounding mode).
//
//  For their correct work, VML functions change floating-point precision and

//  expensive operation, it is recommended to set precision and rounding mode
//  to optimal values before VML function calls.
//
//  VML_FLOAT_CONSISTENT  - use this value if the calls are typically to single
//                          precision VML functions
//  VML_DOUBLE_CONSISTENT - use this value if the calls are typically to double
//                          precision VML functions
//  VML_RESTORE           - restore original floating-point precision and
//                          rounding mode
//  VML_DEFAULT_PRECISION - use default (current) floating-point precision and
//                          rounding mode
