I strongly miss a function to return the number of DISTINCT values existent in a given cell range. To my knowledge, this functionality is missing in every spreadsheet application, although most of the research involves such analysis.

I would be further interested to perform some operations using these distinct values.

Functions: DISTINCT( 'cell_range', AS.TEXT = TRUE, IGNORE.CASE = TRUE) returns number of distinct strings in the cell range

DISTINCT( 'cell_range', AS.TEXT = FALSE, TOLERANCE = 0) returns number of different values DISTINCT( 'cell_range', AS.TEXT = FALSE, TOLERANCE = 0.5, ORDER = "ASCENDING") returns number of different values; values within TOLERANCE are considered EQUAL - values are ranked first using the specified ORDER - IF( x[i] is within TOLERANCE of x[i-1]), the 2 values are considered equal DISTINCT( 'cell_range', AS.TEXT = FALSE, TOLERANCE = '5%', ORDER = "ASCENDING") returns number of different values; values within TOLERANCE are considered EQUAL - values are ranked first using the specified ORDER - IF( x[i] is within TOLERANCE of x[i-1]), the 2 values are considered equal - the absolute value for TOLERANCE is computed as x[i-1] * TOLERANCE

DISTINCT( 'cell_range', AS.TEXT = FALSE, 'cell_range2') returns number of different values within 'cell_range' - 'cell_range2' describes the bounds/intervals used for splitting the initial data (i.e. for splitting 'cell_range') - the values within 'cell_range2' are ranked - IF any value from 'cell_range' < MIN('cell_range2') => this is first group - any value from 'cell_range' is within RANKED(cell_range2)[1] RANKED(cell_range2)[2] => next group - ... - any value from 'cell_range' > MAX('cell_range2') => this is the last group

Of course, DISTINCT() is just one aspect of the analysis. Actually, I am more interested in doing specific calculations based on these distinct groups (like SUM(), COUNT(), ...). I will describe such calculations in a later post.

Sincerely,
