Use floating-point multiplication to handle net slope corrections
Description
The Fixed-Point Designer™ software uses floating-point multiplication to perform net slope correction for floating-point to fixed-point casts.
Category: Math and Data Types
Settings
Default: Off
On Use floating-point multiplication to perform net slope correction for floating-point to fixed-point casts.
OffUse division to perform net slope correction for floating-point to fixed-point casts.
Tips
This optimization affects both simulation and code generation.
When converting from floating point to fixed point, if the net slope is not a power of two, slope correction using division improves precision. For some processors, use of multiplication improves code efficiency.
Dependencies
This parameter requires a Fixed-Point Designer license.
