[comp.sys.ibm.pc.misc] Looking for info about Microsoft mathlibs

Howdy

I am looking for someone who has fairly extensive knowledge about the
implementation of floating point libraries under Microsoft C for DOS 
machines.  The question: Is it possible to use the basic operations 
(+,-,*,/) without referencing startup code.  Alternatively: Can the 
library be rewritten in such a way as to do this.  I am writing an addin
for Lotus 1-2-3.  Because the startup code is the property of the spread-
sheet, it is not available at link time - making use of the Microsoft
library impossible (I think).  Unfortunately, the library Lotus provides
implements these operations using 1-2-3's engine, as a result the operations
run an order of magnitude slower (80 micro sec vs 8).  Speed is absolutely
critical.  Please reply to noble@tenet.Berkeley.EDU, as I rarely read the
ibm and msdos groups.

Thanx
