traits and numeric_limits

[Luis Ibanez]

Hi,

One option to the fact that the header <limits> is
missing in gcc, (it appears only like <climits> and
doesn't contains the declaration for the class
"numeric_limits") is to use the numeric_limits class
defined in vxl/vnl.

It is located in

      vxl/vnl/vnl_numeric_limits.h

It is templated as the standard requires, and has been
specialized for :  int, float and double    respectively in

vxl/vnl/vnl_numeric_limit_int.h
vxl/vnl/vnl_numeric_limit_float.h
vxl/vnl/vnl_numeric_limit_double.h

It seems to have he same elements that are expected
from the standard.


Could that be equivalent to using <limits>
header and numeric_limits  class?




Luis
