067c703c56 Fix a bug in MR_sprintf_float where it would convert 1.8e-10 
runtime/mercury_float.c:
    Fix a bug in MR_sprintf_float where it would convert 1.8e-10
    into "1.80000000000000e-1" instead of "1.8e-10".

    The problem was that it was stripping the zeros off the end of the string
    produced by sprintf without considering the case where the output
    was in scientific notation.

    The fix is to remove the `#' from the sprintf format string and then to
    append ".0" to the string if there is no "." or "e".

    Update the expected output of these tests as trailing zeros are now
    also removed from the base part of scientific notation float strings.

Estimated hours taken: 4
Branches: main

Improve the readability of float output from the debugger and io.print etc.
by pruning redundant trailing zeroes.

NEWS:
	Mention the change.

library/string.m:
runtime/mercury_float.c:
	Make string.float_to_string trim redundant trailing zeroes.
	The behaviour of string.format etc. is unchanged.
