[Gambas-user] numerical error in Gambas??

[Jesper Holm]

Hi Benoit,

I am a little uneasy reporting this, but it seems that the IF..THEN statement 
is testing the "displayed" value and not the calculated value.

PUBLIC SUB Main()
DIM a AS Float
  FOR a = 1.68 TO 1.70 STEP 0.001
    IF (a * (1/a)) = 1 THEN
      PRINT a, (a * (1/a)),"OK"
    ELSE
      PRINT a, (a * (1/a)),"not OK"
    END IF
  NEXT
END

Does prints some "not OK" values. 

Do you know which parts of Gambas is affected by this bug? I have several of 
that kind of tests in my program.

Also the SELECT..CASE and DO..LOOP structures are affected. (but I guess those 
are derived from the IF..THEN)

Hope it can help narrowing down the problem.

Meanwhile I'll just have to use a bunch of ROUND()'s here and there :-)

Jesper
