A small minority, but apparently it includes all the floats you’re likely to use. It seems the insight is that you only need 8 bits of exponent in most cases. (And single-precision floating point only has 8 bits of exponent.) Most double-precision floats are never used because they have high exponents. | ||

Got take, but a double with only 8 bits of exponent actually seems kind of nice, you get the extra precision but it can be cast down to a single and you only lose precision; you don’t have values that are outside the range of singles. | ||
