The lack of full floating point support after all this time in IBM COBOL does 
seem to indicate a decline in its support.  For an example of what full 
floating point support in mainframe COBOL looks like, check out the portable 
open source zCOBOL which runs on Windows, Linux, and Apple OSX.  The compiler 
produces readable HLASM assembler source with data field labels which in turn 
runs on z390 portable mainframe assembler and emulator written entirely in open 
source J2SE java.  zCOBOL supports HFP, BFP, and DFP using the 2002 COBOL 
standard recommended naming conventions for the 9 different floating point data 
types.  Here is link to article with example floating point compute statement 
using all 9 floating point types:
