The FLOAT gate in testFloat allowed only a minus sign on the mantissa, while the exponent right after it already allowed either sign. dynamicTyping therefore left +42 and +1.5E-03 as strings and converted -42 and -1.5E-03, silently producing columns that mix numbers and strings depending on how each row wrote its sign. parseFloat already accepts a leading plus and returns the right value, so the regex was stricter than the conversion it guards. Allow either sign on the mantissa, matching the exponent. The 2^53 precision guard is unchanged, and a plus that is not a sign is still rejected. Fixes #1070
