FloatToFract32

Discussion

THIS MODULE IS DEPRECATED AND NOT RECOMMENDED FOR NEW DESIGNS. PLEASE USE THE TypeConversion MODULE INSTEAD.

This module converts 32-bit floating-point values to 32-bit fractional(Q.31 format) values. The module has N input and N output pins, and the size of the ith output pin must equal the size of the ith input pin.

Floating-point values outside of the allowable fractional range are clipped.

When bypassed the module is still active and continues to perform the conversion.
