9239,"Implicit type conversion without warning, although Wconversion used",Daniel Rings <topwohnung@…>,Matthias Schabel,"When defining a variable with automatic type recognition,
{{{
auto inv_time = 1/si::second;
}}}
this instruction
{{{
inv_time = 0.4/si::second;
}}}
does not generate a warning (using -Wconversion), while
{{{
auto p = 3;
p = 1.0/2.0;
}}}
generates a warning, as it should. Is there any reason for the different behavior in both cases?
It should be mentioned that this is not contingent to ""auto"", for
{{{
quantity<si::time,int>  time = 1/(1/si::second);
time = 0.4*si::second;
}}}
compiles without warning, too (and time = 0 s in the end). I thought implicit typecasts with possible loss of precision were forbidden or would at least trigger a warning.
