In relational operations comparing a floating-point value to
a fixed-point value, the floating-point value is cast to the same
word length and signedness as the

gt function to determine whether the real-world value of one
fi object is greater than another.
a = fi(pi); b = fi(pi, 1, 32); a > b
ans = logical 1
a has a 16-bit word length, while input
b has a 32-bit word length. The
gt function returns
1 because after quantization, the value of
a is greater than that of
Compare a Double to a fi Object
When comparing a double to a
fi object, the double is cast to the same word length and signedness of the
a = fi(pi); b = pi; a > b
ans = logical 0
gt function casts
b to the same word length as
a, and returns
0 because the two inputs have the same real-world value. This behavior allows relational operations to work between
fi objects and floating-point constants without introducing floating-point values in generated code.
