For greater precision Enterprise PLI supports the hardware Decimal Floating Point which is enabled with the compiler option of FLOAT(DFP), this then changes all the DECIMAL FLOAT data declarations to be DFP allowing maximum 34 digits (and exact decimal precision, important for financial applications). The PL/I language itself is unchanged, so existing source code switches to using DFP with a recompile (though changes in DCL might be desirable). Vector DFP is part of ARCH(12) which came with z14. So Enterprise PLI fully supports it already, best I can tell, but doesn't highlight such support in the doc. I do DFP in assembler as I couldn't wait for the compilers to add support and also want finer control (the devil is in the details).
