[To Curt Jutzi -- I, personally, have TRIED to reply to you using the golem!jutz path in your earlier news. The responses have been bounced back from tektronix with a message saying your machine was following an "illegal protocol". I hope this, at least, gets through.] Floating point support exists on the Amiga in several forms for several purposes. The floating point which is directly supported by expression evaluation in the V1.0 release Lattice C for the Amiga is a 64 bit software implementation of the IEEE format. As such, it is *>SLOW<*. The floating point in ABasiC is a 32 bit IEEE format running in a somewhat simpler exception handling environment. Motorola Fast Floating Point format is available (in 32 bits only) in two standard libraries. The fundamental math routines are in the library mathffp which resides in the Writeable Control Store. The corresponding transcendental functions are in the library mathtrans which is disk-based (i.e., it's found in the LIBS: directory and is brought into memory and shared between programs as needed). To access routines in these libraries you do an OpenLibrary() call and then call the desired routine using one of the interface entrypoints defined in amiga.lib. I'll post a working example on the net soon. Yes, we are working with Lattice to make the 32 bit IEEE format and the 32 bit Motorola format routines directly available from the language. -------- We do not expect to make the Amiga schematics public anytime soon. There will, however, be more info available about the timing and characteristics of the expansion bus. Curt, if you have questions about the hardware, I'll try to get them answered. Please be sure to include a phone number so that I don't have to post the replies to the group.

eat your heart out line eater I would be very interested in the hardware info. whether or not i get an amiga or an atari st or stt depends on what hardware info i can get ie. the more info the more useful the machine.. subject to the usual non-disclosure/copyright/patent ect...
