Floating Point

How automation tells CliSiTef that it knows how to handle fields with dots
floating

Treating fields with Floating Point requires a procedure
executed in conjunction with automation.

For Clisitef to carry out this procedure, which will be described below,
it is necessary for the automation to inform Clisitef that it is capable of
treat it. To do this, the automation must pass the string below into the
"ParametrosAdicionais" parameter when executing the function
ConfiguraIntSiTefInterativoEx.

[TrataPontoFlutuante=1]

If this parameter is omitted and SiTef requests field collection with
Floating Point, CliSiTef will ask the automation to display the
message: "Ponto Flutuante nao Suportado pelo PDV".

Procedure in "married operation" with automation

If informed in the Configuration, support the Floating Point feature,
as described above, CliSiTef through Command 0 in conjunction with
o Field Type 2470, informs Automation of the number of decimal places
in the Buffer parameter, so that it can format its screens before
display them to the operator (See Screen Examples on the next page).
Only after this "pact" with Automation, CliSiTef will send the command
field collection with floating point (through commands 34 or 30)
as per examples below.
