Plage

Limitations de la plage, des underflows et overflows, de la saturation et du wrapping

La plage est l’étendue des nombres qu’un type de données à virgule fixe et une mise à l’échelle peuvent représenter. La plage est limitée étant donné que les mots à virgule fixe présentent une taille limitée.

Rubriques

Range and Precision
Range and precision of fixed-point data types.
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.
Underflow and Overflow Logging Using fipref
Examples of using fipref objects to set logging preferences for fi objects.
Handle Overflows in Simulink Models
Control the warning messages you receive when a model contains an overflow.
