number - The number being formatted.

Returns:

abs(number)

composeRuleValue

public double composeRuleValue(double newRuleValue,
 double oldRuleValue)

Returns the additive inverse of the result of parsing the substitution (this supersedes the earlier partial result)

Specified by:

composeRuleValue in class NFSubstitution

Parameters:

newRuleValue - The result of parsing the substitution

oldRuleValue - The partial parse result prior to calling this function

Returns:
