# i <value>:width [int-value]
#
# for integer inputs, or
#
# t <value> <pos> <z> <a>
#
# for noninteger inputs, where <pos> is "a" for fractional part

# with odd integer part and "c" for between 0.5 and 1; <z> is the
# value truncated towards zero, <a> is the value rounded away from
# zero, both being in the form <value>:<width>. Width values are for
