title 87ctriga - C interfaces - asin, acos, atan, atan2
;***
;87ctriga.asm - inverse trig functions (8087/emulator version)
;
; Copyright (c) 1984-89, Microsoft Corporation
;
;Purpose:
; C interfaces for asin, acos, atan, atan2 (8087/emulator version)
;
;Revision History:
; 07-04-84 GFW initial version
; 05-08-87 BCM added C intrinsic interface (_CI...)
; 10-12-87 BCM changes for OS/2 Support Library
; 11-24-87 BCM added _loadds under ifdef DLL
; 01-18-88 BCM eliminated IBMC20; ifos2,noos2 ==> ifmt,nomt
; 08-26-88 WAJ 386 version
; 11-20-89 WAJ Don't need pascal for MTHREAD 386.
