DIGITS

DIGITS (LET)

Let Subcommand

Strip out the individual digits for the integer portion of a number.

Given the number 1423.36, DIGITS will return a vector containing the values 1, 4, 2, and 3.

The negative sign is ignored for negative numbers. That is, DIGITS will return the same values for 1423 and -1423.

This command is a utility function that is used by the Dataplot 10-step macros for analyzing 2-level factorial designs.

LET <y> = DIGITS <a>
where <a> is a parameter or number;
and    <y> is a vector where the digits will be saved.

LET Y = DIGITS 58.6
LET Y = DIGITS A
