To create calculated fields and formulas, you must understand the operators supported by Envision. This section discusses the basic operators.
This means addition when applied to numbers and concatenation when applied to strings. When applied to dates, it can be used to add a number of days to a date.
7 + 3
'abc' + 'def' = 'abcdef'
#April 15, 2004# + 15 = #April 30, 2004#
This means subtraction when applied to numbers and negation if applied to an expression. When applied to dates, it can be used to subtract a given number of days from a date. Hence it can also be used to calculate the difference in days between two dates.
-(7+3) = -10
#April 16, 2004# - 15 = #April 1, 2004#
#April 15, 2004# - #April 8, 2004# = 7
This means numeric multiplication.
5 * 4 = 20.
This means numeric division.
20/4 = 5.
