Pedro Vicente Nunes b269dbf0ae [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

Misc. update:
2006-03-22 15:53:05 -05:00

* Return:
* 0 : no differences found
* 1 : differences found
