Data Conversion seems inconsistent

esirjhm — Thu, 25 Aug 2011 15:33:27 GMT

The following code seems to have two different results with a 10.5 format when the two values in hexidecimal are identical. What am I missing?

DATA TEST;

HMWID = 62.7;

LIN_FT = 1;

RUN;

DATA AVAL (KEEP = K FT);

ARRAY LAR{240:799} _TEMPORARY_;

SET TEST END=END;

PUTLOG HMWID=10.5 +3 HMWID=HEX16.;

HMWID = HMWID * 10;

PUTLOG 'STORING VALUE ' HMWID=10.5 +3 HMWID=HEX16.;

LAR{HMWID} + LIN_FT;

IF END;

DO J = 240 TO (799-40);

K = J;

FT = LAR{J};

IF FT THEN DO;

OUTPUT AVAL;

PUTLOG 'RESTORING VALUE ' K=10.5 +3 HMWID=HEX16.;

END;

RUN;

Output results...

HMWID=62.70000 HMWID=423EB33333333333

STORING VALUE HMWID=627.00000 HMWID=43272FFFFFFFFFFF

RESTORING VALUE K=626.00000 HMWID=43272FFFFFFFFFFF

Doesn't look like anything is wrong. Don't unerstand why you're showing for RESTORING K not being 627.

What's posted looks like an excerpt from a much larger program, perhaps the culprit is elsewhere and got edited out.

By the way, display format, like 10.5, have nothing to do with internal precision.

2 HMWID = 62.7;
