Decimal separator vs. Thousands separator

Being an international journal, and to avoid confusions, NNTDM follows international conventions and standards. The SI metric advises the following:

  • Thousands separator is NON-BREAKABLE SPACE (not point or comma).
    • In Latex, use the symbol ~
    • In MS Word, use the key combination: Ctrl+Shift+Space 
  • Decimal separator is POINT (not comma).
