How to increase decimal places

GAMS
1

Dear GAMS users!
Hope you are all fine.
I have written a code in GAMS and hopefully it works well.
But the point is that i want the results to be more precise.
GAMS gives the value of 0 to those variables which have a decimal places of 0.001 (may be less than than i am not sure)
How is it possible to increase the decimal places of the results that GAMS shows?
As i searched the menus, it is possible to have decimal places of 7 but that doesn’t satisfies me i want more precision than that.
Some of the variables i work with have more than 15 zeros after decimal.
I also tried to exporting variables to Excel and then increasing the decimal places in Excel, but it didn’t work. Because GAMS exports non-zero variables and so those with high decimal places take the value of zero and keep their value during exportation to GAMS.
Don’t you have an idea?
Looking forward for your nice soloutions;
Cordially;
Ali Zarrineh

  1. I think you must use the option decimals = n to change it the n decimals. And you can give n the value 30 or 20 to n.

  2. For example you can write option decimals=30.

As Herve said, you can use OPTION DECIMALS = n. But I don’t think GAMS allows decimal places greater than 8, does it? This question was posted a couple of days ago but the fact is up to now the maximum decimal places supported in GAMS is 8.

Best wishes,
Destin

Ali,

I googled “GAMS put decimals” and found the link below: it has lots of
relevant and helpful info.
