Hi ,

After reading Sergey Message #838548 and mskb #258998
i test numeric behaviour.

CLEAR
SET DECIMALS TO 18
SET FIXED ON
lnDiff = {^2000-03-20 11:31:00} - {^2000-03-20 10:25:00}

zz=3959.999965131283
ww=m.zz+0.000000000000
* i cannot see any difference with DISPLAY MEMORY
DISPLAY MEMORY LIKE lnDiff
DISPLAY MEMORY LIKE zz
DISPLAY MEMORY LIKE ww
* i cannot see any difference with direct print
? lnDiff,ww,lnDiff-ww
* but INT() see a internal difference and not return aspected value
? INT(ww),INT(lnDiff)

* changing syntax for identical computation, change return value

? INT(lnDiff+0.0),INT(lnDiff+0.00),INT(lnDiff^1)
? MOD(lnDiff*1,1),MOD(lnDiff*10,1),MOD(lnDiff*100,1)
? BETWEEN(lnDiff,3960,3960.00),BETWEEN(lnDiff,3960.00,3960)
* i can continue

On past i know this:
numeric variable have a value,
and have a format set by origin value used for display

Now i known this:
numeric variable have a value,
and have a format set by origin value used for display
AND VFP FUNCTIONS USE VARIABLES VALUE, VARIABLES FORMAT AND SCRIPT
SYNTAX FOR RETURN THE RESULT.

But the format of variable is invisible.
