[svn-r8283] Purpose:
bug fix (sort of)

Description:
apparently linux and other systems (solaris) return a different value from atof if the
argument is in  hexadecimal .
this return value was used to test if the argument to -p and -d was a valid floating point
number
for now , commented the calls in the script with -p <hexa> until we find a portable solution

Solution:

Platforms tested:
linux
solaris
windows

Misc. update:
