tests/float: Improve formatfloat.c test coverage using Python. 2017-01-04 19:06:12 -05:00			`# uPy and CPython outputs differ for the following`
			`print("%.1g" % -9.9) # round up 'g' with '-' sign`
py/formatfloat: Fix number of digits and exponent sign when rounding. This patch fixes 2 things when printing a floating-point number that requires rounding up of the mantissa: - retain the correct precision; eg 0.99 becomes 1.0, not 1.00 - if the exponent goes from -1 to 0 then render it as +0, not -0 2017-06-12 23:36:56 -04:00			`print("%.2g" % 99.9) # round up`
