FINDU Formulator function
Find up searches up the column until it finds a value that matches the user-specified value X. It then returns the
row number (index) of that value. FINDU searches a column (vector) V, beginning at START. Then it returns the
row number (index) of that value.
Usage
FINDU(V, X, STARTPOS)
V
The name of any column (vector) listed under Columns
X
Any value, which may be the result of another calculation
STARTPOS
The row number (index) of the starting value for the search
Details
If FINDU does not find an exact match for X, it returns the row number (index) of the V value that is
closest to X.
Example
IF = AT(ANODEI, FINDU(ANODEV, 0.7, LASTPOS(ANODEV)))
