How rules work

The following sections describe how rules work within TM1® and provide considerations you should keep in mind when you develop rules.

Calculate on demand
TM1 calculates values only when requested, or on demand.
Precedence of rules statements
When more than one statement in a set of rules applies to the same area, the first statement takes precedence.
Rules and dimension consolidations
Rules work in concert with consolidations defined in dimensions.
Comparing floating point numbers
Due to the "floating point" representation of numbers, some numbers such as .35 turn into .34999999999999998 when stored in a binary format.
