WebJan 30, 2024 · Because powers of two are shifts in fixed point, is possible to rewrite the expression as (with Verilog notation): x_fixed = ( {1'b1, m [22:7]}) << (exp - 126) Ok, this works perfectly, but not all the times... The problem here is: How can I apply nearest rounding? I have performed experiments to see what happens, in different ranges.

If you multiply those numbers as integers, the LSB Xf+Yf bits of the integer result could be treated as fractional bits of resulting fixed-point number (and you still multiply them as integers).
