Editing Point data

Point Attributes store numbers that can have decimal places.

Examples (with decimal point) :

  • Enter 0.400 to store/display 0.400
  • Enter 1.2300e5 to store/display 123000
  • Enter 24. to store/display the value as 24
  • Enter 27.0 to store/display 27.0

Values are stored to a maximum of 15 significant figures and must be within the range:

  • 1.5e-45 to 3.4e38
  • 1e-039 to 1e+038 for positive values

Point Attributes can store and display trailing zeros at the end of a numerical value, allowing the correct representation of data where precision is important. The significant zero is indicated by an overbar. To use trailing zeros, when entering data, type in the decimal separator (plus any zeros).
