Equality Absolute Tolerance

Type

Floating point number

Range

[0, 1]

Default

0

For two real numbers x and y the result of the comparison x < y (or any of the other relational operators =, <>, >, >=, or <=) depends on two tolerances:

  • Equality Absolute Tolerance, and

  • Equality Relative Tolerance.

For a detailed description of these two tolerances and numerical comparison in AIMMS, you should read the corresponding section in the Language Reference.

Note

  • This option has no influence on the feasibility of constraints.

  • This option influences assignments in the following way; when a value is assigned to an identifier that is equal to the default of that identifier, equal within the above tolerances, the assignment will be ignored.

  • This option also affects WinUI objects that display a numerical value as a check box (such as check box columns in a table). The check box is shown as unchecked only if the value is equal to zero within this tolerance. A value that is close to zero but exceeds this tolerance is therefore treated as nonzero and shown as checked.

  • The DISPLAY statement shows values within this tolerance as 0. Values outside this tolerance are shown as they are stored.
