The ABS function evaluates the absolute value of the enclosed expression and simplifies the expressions.
Example
You can simplify the following expression
((NetAmount+VAT-Total)<0.02)&&((NetAmount+VAT-Total)>(-0.02))
by using the ABS function to
ABS(NetAmount+VAT-Total)<0.02
When using constant values in an expression, such as ABS (NetAmount+VAT-Total)<0.02, always use a period as decimal separator and do not use thousand separators.
