Compiler Option: -fpmode

Selects faster, less accurate or slower, more precise floating-point math.

Syntax
   -fpmode < mode >

Parameters
   mode
      The floating point mode: FAST | PRECISE.

Description
   The -fpmode compiler option specifies whether speed or precision is more 
   important for floating point math. If this option is not specified, the 
   default is -fpmode PRECISE.

   -fpmode FAST will generate faster, less accurate instructions for 
   certain floating point operations.

   -fpmode PRECISE will generate standard floating point instructions that 
   operate at the default speed and accuracy of the selected floating point 
   unit.

   Currently, the only floating point operations that behave differently 
   when using -fpmode FAST are: Sin(), Cos(), reciprocal, and reciprocal 
   Square Root, all of which must operate on Single precision values.

   Using -fpmode PRECISE is dependent on the -fpu SSE command line option. 
   Using -fpmode PRECISE without using -fpu SSE will generate an error.
