    Abstract - (Show below) - (Hide below)

    Sets out rules for the rounding of numbers, the number of significant figures to be retained in presenting any particular value, and conventions concerning the interpretation of specification limits in relation to their mode of expression. General principles and working rules relating to different aspects of this subject are set out and illustrated with examples.

    Scope - (Show below) - (Hide below)

    This standard deals with certain aspects of the rounding and interpretation of numerical values. It includes the following: (a) Rules for the rounding of numbers (assuming a prior decision on the appropriate number of figures to be retained) (see Section 3).(b) A discussion of the number of significant figures to be retained in presenting any particular value (see Section 4).(c) Conventions concerning the interpretation of specification limits in relation to their mode of expression (see Section 5).
