Replace column by random number addition

Here is my problem:-

I have a file with pipe separated values.

Code:
CR|20121021|079|ABC|N|DLS|00038|DLS|04750|1330597704|634234|634|0

Now I want to replace field: 10 (highlighted) by adding a random number to field number: 11. But the random number has to be generated based on decimal places of field: 11

E.g: In the first record, the 11th field value is 634234, so we have to generate a 4 digit random number and add to field number 11.

Hence if 11th field is

6 digits - random number should be 4 digits
5 digits - random number should be 3 digits
4 digits - random number should be 2 digits
3 digits - random number should be 1 digits

Please assist.

NAME
plgxax - Get x axis parameters SYNOPSIS
plgxax(digmax, digits) DESCRIPTION
Returns current values of the digmax and digits flags for the x axis. digits is updated after the plot is drawn, so this routine should only be called after the call to plbox(3plplot) (or plbox3(3plplot)) is complete. See the PLplot documentation for more information. Redacted form: plgxax(digmax, digits) This function is used in example 31. ARGUMENTS
digmax (PLINT *, output) Pointer to variable with the maximum number of digits for the x axis. If nonzero, the printed label has been switched to a floating point representation when the number of digits exceeds digmax. digits (PLINT *, output) Pointer to variable with the actual number of digits for the numeric labels (x axis) from the last plot.
