Editing Range data

Range data may be entered as an integer or decimal, or formatted with an exponent.

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

  • ±1.5×10-45 to ±3.4×1038
  •  1e-039 to 1e+038 for positive values  

Range 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).
