WebNov 28, 2024 · This means that at each exponent value, you can test all 2^23-1 (roughly 9mil cases) possible combination of binary representation (give or take). Then you do it for all exponent value (255 values), and you can basically cover all floating points represented by IEEE. However, for double precision, such approach is not really viable. WebApr 3, 2016 · Suppose you store floating point values as 6 signed digits with a signed 2 digit power of 10 exponent. for example, 123456 07 means 123456x10 7. The 6 digits is …
