Typ: Vordefiniertes Symbol

__FB_FPMODE__ ist ein Symbol mit vordefiniertem Wert "fast". Dieses Symbol wird definiert, wenn der Compiler 'SSE floating point arithmetics' compiliert. Dazu ist die Compiler-Option -fpu SSE nötig.

Beispiel:

#IFDEF __FB_FPMODE__ = "fast"

  '... Anweisungen für "fast" floating point instructions

#ELSE

  '... Anweisungen für "normal" floating point instructions

#ENDIF

Unterschiede zu QB: neu in FreeBASIC

Unterschiede zu früheren Versionen von FreeBASIC: existiert seit FreeBASIC v0.16

Unterschiede unter den FB-Dialektformen:
In der Dialektform -lang qb steht __FB_FPMODE__ nicht zur Verfügung.
