Numerical range of `fi`

or `quantizer`

object

`fi`

ObjectIf `q`

is a floating-point `quantizer`

object,
`min_q = -realmax(q)`

and `max_q = realmax(q)`

.

If `q`

is a signed fixed-point `quantizer`

object
`(datamode = 'fixed')`

, then

*min_q* = −realmax(*q*) −
eps(*q*) =
−2^{w−1}/2^{f}

*max_q* = realmax(*q*) =
(2^{w−1} − 1)/2^{f}

where *w* is the word length and *f* is the fraction
length.

If `q`

is an unsigned fixed-point `quantizer`

object
`(datamode = 'ufixed')`

,

*a* = 0

*b* = realmax(*q*) =
(2^{w} − 1)/2^{f}

See `realmax`

for more information.
