Strange problems on decimals - dangerous bug !!

[Marco Turco]

Tried your code but I always got error.

Change the name of the var, nTest_Decimals := 3

Code: Select all  Expand view  RUN

#include "fivewin.ch"

procedure start()
Local nTest_Decimals := 3

oSQLite := TSQLiteServer():New( "test.sql" )
If oSQLite:lError
msgStop( "error" )
RETURN
EndIf

cQuery:="SELECT * from t_tables;"
oQry:=oSQLite:Query(cQuery)
nTest_Decimals :=oQry:aData[1,7]
oQry:End()
oSQLite:End()

msginfo(nTest_Decimals ) && return 3
msginfo(valtype(nTest_Decimals )) && return N

msginfo(str(88.456,10,3)) && return 88.456
msginfo(str(88.456,10,nTest_Decimals )) && RETURN 88 !!!



return
function gettemppath()
return("")

I have an off topic question. Where did/does the TSQLiteServer() class come from? I've searched high and low and have not yet come across this.

Thanks in advance.

What error?

All I did is replace nDecimals by nTest_Decimals

[Marco Turco]

For error I mean that msginfo(str(88.456,10,nTest_Decimals )) Always return 88

Try this now...
I included Set Decimals 20, Set Exact On, extra debugs to trace the value of nTest_Decimals

Code: Select all  Expand view  RUN

#include "fivewin.ch"

procedure start()
Local nTest_Decimals := 3, nBkpDecimals := -999

   Set Decimals to 20
   Set Exact on

   oSQLite := TSQLiteServer():New( "test.sql" )

   If oSQLite:lError
      msgStop( "error" )
      RETURN
   EndIf

   cQuery:="SELECT * from t_tables;"
   oQry:=oSQLite:Query(cQuery)
   nBkpDecimals := nTest_Decimals
   nTest_Decimals :=oQry:aData[1,7]

   If nTest_Decimals == nBkpDecimals
       MsgInfo("Identical values")
   else
       MsgInfo("Compare decimals values")

       If AllTrim(Str(nTest_Decimals,25,20)) != AllTrim(Str(nBkpDecimals,25,20))
           MsgInfo(AllTrim(Str(nTest_Decimals,25,20)),"nTest")
           MsgInfo(AllTrim(Str(nBkpDecimals,25,20)),"nBkp")
      else
           MsgInfo("Equal strings")
       end


   End

   oQry:End()
   oSQLite:End()

   msginfo(nTest_Decimals )
   msginfo(valtype(nTest_Decimals ))

   msginfo(str(88.456,10,3)) && return 88.456
   msginfo(str(88.456,10,nTest_Decimals )) && RETURN 88 !!!

return

function gettemppath()
return("")

Hi sambomb,
i did your test. Identical value but it return always 88.

You can download source and executable from http://109.228.12.120/softwaredistribut ... /test3.zip

Marco,

Please try so:

Code: Select all  Expand view  RUN

...
nTest_Decimals :=oQry:aData[1,7]

nTest_Decimals := Val( Str(nTest_Decimals, 10))               //  <---- New
...
 

Regards

Marco,

Did you ever find a solution?

It looks like hmpaquito's idea might work. Did you try it?
