What Does it Do ?
Absolute reference function calculates the value of a number, irrespective of whether it is positive or negative.

Syntax

=ABS(CellAddress or Number)

Formatting

The result will be shown as a number, no special formatting is needed.

Example
The following table was used by a company testing a machine which cuts timber.
The machine needs to cut timber to an exact length.
Three pieces of timber were cut and then measured.
In calculating the difference between the Required Length and the Actual Length it does
not matter if the wood was cut too long or short, the measurement needs to be expressed as
an absolute value.

Table 1 shows the original calculations.
The Difference for Test 3 is shown as negative, which has a knock on effect
when the Error Percentage is calculated.
Whether the wood was too long or short, the percentage should still be expressed
as an absolute value.
