[Scilab-users] A possible bug with format(width)

[Stéphane Mottelet]

This behavior (swith to "e") is logical. For example, with 
format("v",10), which is the default, 123456789 cannot be displayed in 
"v" mode with 10 characters. Hence, the only solution is to switch to 
"e" mode:

--> format("v",10)

--> 123456789
  ans  =

    1.235D+08

Of course, you cannot use less than 7 characters (3 chars for the signed 
mantissa and the dot and 4 chars for the exponent):

--> format("v",8)

--> 123456789
  ans  =

    1.2D+08


--> format("v",7)

--> 123456789
  ans  =

    1.D+08


--> format("v",6)

--> 123456789
  ans  =

    1.D+08
