#
# Auxiliary routine to be sourced by
# suite/funcs_1/t/storedproc.test
#
# Purpose:
#    The assignment of float values to objects of type DECIMAL causes
#    conversions and in some cases an adjustment of the value to
#    a border of the value range.
#    Try to reveal that function and procedure parameters get a similar
#    mangling of the value like columns.
#    
# Variables to be set before sourcing this routine
#    $test_value  - value to be checked

# added --disable / --enable_warning statements to minimize differences
# between platforms (Bug#40177 Test funcs_1.storedproc failing on Pushbuild)
#
# TODO:  (After 5.1 GA)
# 1)  Examine reordering statements in this file to minimize the number of
#     --disable / --enable_warning statements.  Unsure if performance gains
#     warrant the working time
# 2)  We could probably add a comparison of the # of warnings before the
#     assignment of @v1_proc and @v1_func to the # of warnings after assignment
#     The difference of these values should be zero
# Refer to Bug#40177 - http://bugs.mysql.com/bug.php?id=40177 for notes as well
