WebOct 21, 2014 · Floats in IEEE-754 are represented with a 8 bit exponent and a 23 bit mantissa. That excludes the hidden bit, which is always 1 (except for denormals or NaNs or 0), so the mantissa (significand) is usually 24 bits, but only 23 are stored. The diagram shown is almost correct for little-endian floats. WebFloat (parade), a decorated vehicle or moving platform, could be animal- or man-drawn or motorized, used in a festive parade.
