| 3.How to solve the round-off Issue? |
Problem: When we round off the float value using format$() function it return value have the floating point issue.
Example:
pprint format$("10.1",1.75) ''Return 1.8
pprint format$("10.1",1.075) ''Return 1.07
In the above example the first pprint we are round 2 decimal points of 1.75 value using format$() function return 1.8 correct value, but the same format$() function is used to round off 2 decimal points of 1.075 return 1.07 wrong values , correct value is 1.08 . This is sample .01 floating point issue .
Work-Around:
When we are getting Floating issue, Please Use the following function behalf of use format$() function . It return the correct values.
Function Call
pprint FormatCurrency$("10.1",1.075) ''Return 1.08
Function Definition
functionS FormatCurrency$(DimF Val)
FormatCurrency$=format$("10.2",ROUND((val*1000)/10)/100)
end function
Note: This is not an VM Issue because we tried the same thing in C++ the same result we are getting .

| 4.When we pass the sub-routine arguments as parameter to CallLibFuncPas( ) function it return error. |
Problem:
When we pass the sub-routine arguments as parameter to CallLibFuncPas( ) function it return error.
Example:
Function Call:
call setposition(200,200,100,100)
Function Definition:
sub setposition(width,height,xx,yy)
dimi hwnd,h,flag,hwndA
if GETOSVAR$("*PLATFORM")="PPC" then
h=loadlib("coredll.dll")
else
h=loadlib("user32.dll")
endif
hwnd=atol(getosvar$("*hwnd"))
flag=64
hwndA = -2
CallLibFuncPas (h,"SetWindowPos",hwnd,hwndA,xx,yy,width,height,flag)
unloadlib(h)
setosvar("*setwindowstyle", "268435456")
End Sub
In the above example ,call sub-rountine “sub setposition(width,height,xx,yy)” pass integer parameters (In sub-routine assign the parameters to CallLibFuncPas() function call) it return “string values “ expected Error.
Work-Around:
Suggestion 1:
Function Call:
call setposition(200,200,100,100)
Function Definition:
sub setposition(int width,int height,int xx,int yy)
dimi hwnd,h,flag,hwndA
if GETOSVAR$("*PLATFORM")="PPC" then
h=loadlib("coredll.dll")
else
h=loadlib("user32.dll")
endif
hwnd=atol(getosvar$("*hwnd"))
flag=64
hwndA = -2
CallLibFuncPas(h,"SetWindowPos",hwnd,hwndA,xx,yy,width,height,flag)
unloadlib(h)
setosvar("*setwindowstyle", "268435456")
End Sub
In the function definition “setposition(int width,int height,int xx,int yy)” parameters define with data type . Its working fine.
Suggestion 2:
Define option() function pass the parameter value 1 in the page.
Better Work-Around solution use Suggestion 1 because some of the time we do not want to use option() [Suggestion 2 ].
