##
#Y  Copyright 2011,   The GAP Group
##  to be listed in testinstall.g
##  these tests deal with various cases in long integer parsing where the number has
##  to be read in one two or three blocks, which may sometimes be exactly filled or
##  sometimes end with a partial block.
##
##  To be extended with similar tests for all the cases of float and long-float 
##  parsing when I have a reliable way of testing them.
