Comma to dot

Hi im using LibreOffice in Greece. I have a problem that I dont know how on Calc :
I have numbers like 123456,09 and I want to insert them into a cad program.
How I can change that coma to a dot. (123456.09 correct form to insert to CAD) ?

By the way: Can’t you set the CAD program to accept decimal numbers with the comma as the decimal separator?

Use a cell style with English format settings, which will have a decimal point instead of comma (Format settings Numbers> Language)

You needn’t change that. LibO Calc will do it for you.

-1- Select the range containing the numeric results or contents you want to copy and to paste to a different application.
-2- > ‘Format’ > ‘Cells’ > tab ‘Numbers’
-3- There you can use a dropdown list under ‘Language’ to select a language. Choose ‘English (UK)’ e.g.

The language (in fact a “locale”) is associated with rules concerning the display of numeric values. For English locales this will include the usage of the point as the decimal separator.

(Sorry. Posts crossed. A named cell style is clearly preferrable over direct formatting.)
