MISTAKE: <q>abs(value)
The absolute value of a value.
Supported value types: Float, Integer, String, Text, Log.
For strings returns: 0 - the values are equal; 1 - the values differ.
Parameter:
value - the value to check
The absolute numeric difference will be calculated, as seen with these incoming example values ('previous' and 'latest' value = absolute difference): '1' and '5' = 4; '3' and '1' = 2; '0' and '-2.5' = 2.5</q>
COMMENT: is this true? I thought this function only calculate absolute value, not compare anything (function 'change').
