Hi all,

Question:
How to format a number in ferret ?

Answer:
Use a spawn command to run the shell script format_number

Examples:

yes? let var=3
yes? let var_formatted =  {SPAWN:"echo `var`  | format_number %05d"} ; 
list var_formatted
       "00003"

yes? let var=3.14
yes? let var_formatted =  {SPAWN:"echo `var`  | format_number %.3e"} ; 
list var_formatted
       "3.140e+00"

Usage of format_number shell script is:
format_number gawk_format_specifier

How that will help
