Issue description

In the script editor, selecting an expression and pressing the shortcut for Evaluate Selection does just what the name suggests, e.g. selecting 10+24 will transform the selection into 34. However, for larger numbers, or any number where you put underscores for readability, e.g. 500+10_000, all characters starting from the underscore are ignored, which results in 510 instead of 10500.

Steps to reproduce

• Type an expression in the script editor, with one number containing an underscore.
• Press the Evaluate Selection shortcut (or select it from the context menu).
• The result will not consider any characters after the underscore and will simply remove them.
