Question
Write down the IEEE 754 single, double precision format representation
Solution
The IEEE 754 standard represents floating point numbers in binary format. It has two types of precision format: single precision and double precision.
-
Single Precision Format:
- Sign bit: 1 bit
- Exponent: 8 bits
- Mantissa: 23 bits The single precision format is represented as 1 sign bit, 8 exponent bits, and 23 mantissa bits. The sign bit is 0 for positive, 1 for negative. The exponent is biased by 127, meaning that 127 is subtracted from the actual exponent to get the stored exponent. The mantissa is represented as a binary fraction.
-
Double Precision Format:
- Sign bit: 1 bit
- Exponent: 11 bits
- Mantissa: 52 bits The double precision format is represented as 1 sign bit, 11 exponent bits, and 52 mantissa bits. The sign bit is 0 for positive, 1 for negative. The exponent is biased by 1023, meaning that 1023 is subtracted from the actual exponent to get the stored exponent. The mantissa is represented as a binary fraction.
In both formats, the value of the floating point number is calculated as (-1)^sign * 1.mantissa * 2^(exponent - bias).
