I use C locale, where the decimal point is a period. Evaluating the
string "2+2" gives the result 4, because the String has been evaluated
as an expression. Similarly, evaluating the String "1.200000", which is
also the string-representation of an expression, gives "1200000" which
is the result of that expression -- a concatenated String. OTOH,
eval("1,200000") gives an error "Trailing characters" because 1,200000
cannot be seen as ONE expression -- i.e., "when we're finished parsing
it, there's something left over", namely the comma and everything after it.
If you had used ":let c = str2float(b)" then (IIUC -- I didn't try) the
result would have come out equal to a. In a "decimal comma" locale,
eval('&' . b) wouldn't have worked, you would have had to first replace
the comma by a dot.
Best regards,
Tony.
