Obtain minimum NEGATIVE float value in C++

Question

I was looking at std::numeric_limits::min/max() but it appears \'min()\' returns the smallest absolute value, not the lowest value. Is it safe

Answer 1

Yes, float is symmetric in minimum/maximum values.

If you're using the lowest representable value as an initial value in searching a list for its maximum value, consider using infinity instead.

std::numeric_limits::has_infinity() will return true for any numeric type that has it and std::numeric_limits::infinity() will return a value that always evaluates greater than any other non-NaN value for that type. This value can be negated and will evaluate less than anything else.
