WebIf not, positive. The exponent is modified by something called "the bias", so we can't simply store "0000 0010" as the exponent. The bias for a single precision floating point number is 127, and the bias for a double precision (this is where the double datatype gets its name) is 1023. The final 23 bits are reserved for the significand. WebThe exponents 000 16 and 7ff 16 have a special meaning: . 00000000000 2 =000 16 is used to represent a signed zero (if F = 0) and subnormal numbers (if F ≠ 0); and; 11111111111 2 =7ff 16 is used to represent ∞ (if F = 0) and NaNs (if F ≠ 0),; where F is the fractional part of the significand.All bit patterns are valid encoding.
