You can do the same using a union with an integer and one real.

There is'nt any calculation. We only have told the compiler that the 64 bits are a real number representation.

If your real value (a) is strored in an int (intVal). Do:

B:pointer to real;

B:=adr(intVal)

A:=B^

hi:
Sorry for not explaining myself well, my English is not good.
I make a simple application with three variables with the same value (value=10) INT, REAL, LREAL in the visualization it looks perfect all read perfect.
Now download /var/opt/codesys/Plcprogram/trend/Application.Test.sqlite ( the trend record is called Test).
open this archive with mozilla firefox sqlite manager.
The variable INT is record perfect, the records is 10
The variable REAL, the records is 1092616192
the variable LREAL, the records is 4621819117588972000

my problem is that I do not know how to do this conversion and I need to save values with decimals.
If something does not explain me well, tell me
thank you very much for taking your time.

hello:
doing tests I have verified that the problem is with the real values since the database in sqlite is built with all the variables in type INT. Someone can help me that the database has the types corresponding to its variables or how to pass the value that gives you from a real variable the database to the real data.
Thank you very much, it would be very helpful ...
None?

I downloaded a sqlite file from the one that generates the trend register, it gives me the time in TS and the value, but I do not know in what format it is returned because a value of 210 gives me a record of 1131986942 in the value field.

best regards,
