The range is the span of numbers that a fixed-point data type and scaling can represent. Range is limited because fixed-point words have limited size.
- Range and Precision
The range of a number gives the limits of the representation, while the precision gives the distance between successive numbers in the representation. The range and precision of a fixed-point number depend on the length of the word and the scaling.
- Saturation and Wrapping
Saturation and wrapping describe a particular way that some processors deal with overflow conditions.
- Determine the Range of Fixed-Point Numbers
Fixed-point variables have a limited range because digital systems represent numbers with a finite number of bits.
- Guard Bits
Eliminate the possibility of overflow by appending the appropriate number of guard bits to a binary word.
