[svn-r12134] Purpose:

bug fix

Description:
1) added a more explainative usage message
2) the percent relative error for the integer type (division) was being done using integer arythmetic; use floating point arythmetic instead
3) added a new test for integer percent

Solution:

Platforms tested:
linux (32,64)
AIX
solaris
