Change scaling of fi
object
b = rescale(a, fractionlength) b = rescale(a, slope, bias) b = rescale(a, slopeadjustmentfactor, fixedexponent, bias) b = rescale(a, ..., PropertyName, PropertyValue, ...)
The rescale
function acts similarly to the fi
copy function with the following
exceptions:
The fi
copy constructor preserves
the real-world value, while rescale
preserves the
stored integer value.
rescale
does not allow the Signed
and WordLength
properties
to be changed.
In the following example, fi
object a
is
rescaled to create fi
object b
.
The real-world values of a
and b
are
different, while their stored integer values are the same:
p = fipref('FimathDisplay','none',... 'NumericTypeDisplay','short'); a = fi(10, 1, 8, 3)
a = 10 numerictype(1,8,3)
b = rescale(a,1)
b = 40 numerictype(1,8,1)
stored_integer_a = storedInteger(a); stored_integer_b = storedInteger(b); isequal(stored_integer_a,stored_integer_b)
ans = logical 1
