I'm too lazy to all that work. I cheat (a lot). But my cheating does require that my HLASM code be LE enabled, or use CEEPIPI to establish an LE environment. I find the former to be easier. Once I do that, I can use the C subroutine "SPRINTF" to do my conversion from floating point to printable. Well, I don't actually do floating point. I do other conversions. The C calling sequence is a bit of a bother, but once learned, it is not too difficult to use.
On more recent z machines (but I don't know what level) there is an HFP "convert to fixed" set of instructions. However, they round to an integer. So you'd need to scale the floating point by multiplying by an appropriate factor of 10 before doing the instruction. The instructions are CFER - short HFP to 32 bit integer CFDR - long HFP to 32 bit integer CFXR - extended HFP to 32 bit integer CGER - short HFP to 64 bit integer CGDR - long HFP to 64 bit integer CGXR - extended HFP to 64 bit integer These are all <opcode> <gen_register>,<mask>,<float_register> where mask specifies the rounding 0 - towards 0 1 - invalid 2 - invalid 3 - invalid 4 - to nearest, ties go towards zero 5 - to nearest, ties go towards even 6 - to +inf 7 - to -inf On Thu, Jul 25, 2013 at 2:38 PM, Dr Rick Williams < dr.rick.willi...@gmail.com> wrote: > I have a prohram that prints some specific SMF data, that I use for > charting & graphing.
