# The general testcase syntax is
# assertionType expectedValue functionUnderTest [args ... ]
#
# where assertionType is either of:
# Code to indicate the (bash-style) integer return code
# String to indicate the string "printed" as a side effect
#
# and functionUnderTest is the function name
# with the "_shellmath_" prefix removed.
