reporting a bug in AWK

[pietro . nicolaidi]

Dear FSF,

here the description of what seems to be a bug in AWK. (I'm not able to find out if I'm using your awk or that of Solaris).
(Please ignore the other one in the mail below. Mr Henek from ATComputing <my  teacher of basic Unix> has already clearifeid that it was due to my misuse of awk.)
Thanks in advance,

P A Nicolaidi

                           if( diff[j,i] > alt[i]  )
This "if" "condition" result (erroneously) matched from the following data.

      alt[i]    is == 0.1            (I have no moer the right value)
and 
    diff[i,j] is 3.3465e-05   (I have no moer the right value)

[it seems that it reads   diff[i,j] as == 3.3]
 

This "if" works correclty id  d[i,j] is 0.0003465
[it understands that 0.0003465 is less than 0.1]

Dear FSF,



I have found this two bug in AWK (I'm not able to find out if it is the gnu AWK or something else). 

Hoping it is useful.

                                        FIRST CASE

------------------------------------------------------------------------------------------------------------------------------
FROM THE CODE
   
>  dati_XP0101 =  $0                                                                   # here "$0" has as value a "string", that is the name of a "data-file" in the current "directory"
>            while ( (getline < dati_XP0101  ) > 0)                       # here I'm reading the "lines" of the "data-file"
>                {
>
>#         if ($1 == VIMS1FV01)   per qualche ragione questo 
this last line returns strange results, when it trys to analyzes  the line ",0.000" from the data-file.

>           if  (match($1,"VIMS1FV01")==1)
this last line, instead, works correclty, and is triggered only by the data-file-line "VIMS1FV01,-3.8821e-03"


FROM THE DATA FILE  (

><EOH>
>XP0101_MON,,1,1
>Single,0,0
>, 0.0000e+00
>, 0.0000e+00
>, 0.0000e+00
>, 0.0000e+00
>VIMS1FV01,-3.8821e-03

--------------------------------------------------------------------------------------------------------------------
NEXT  CASE

                           if( diff[j,i] > alt[i]  )
This "if" "condition" result (erroneously) matched from the following data.

      alt[i]    is == 0.1            (I have no moer the right value)
and 
    diff[i,j] is 3.3465e-05   (I have no moer the right value)

[it seems that it reads   diff[i,j] as == 3.3]
 

This "if" works correclty id  d[i,j] is 0.0003465
[it understands that 0.0003465 is less than 0.1]
