I have tried to enter 6E5 in several spaces on my spreadsheet and every time I enter it, it gets changed to ### when I hit my enter key. It has accepted other 3 characters groups without a problem. For some reason it just won’t accept 6E5. I am running an Apple computer with 10.9.5 Mavericks using version 184.108.40.206 Libreoffice. I thought it might be a glitch in Libreoffice.
