At program startup the floating-point environment is initialized as prescribed by IEC 60559:

  • All floating-point exception status flags are cleared.

  • The rounding direction mode is rounding to nearest.

  • The dynamic rounding precision mode (if supported) is set so that results are not shortened.

  • Trapping or stopping (if supported) is disabled on all floating-point exceptions.
