Square root of fi
object
c = sqrt(a)
c = sqrt(a,T)
c = sqrt(a,F)
c = sqrt(a,T,F)
This function computes the square root of a fi
object
using a bisection algorithm.
c = sqrt(a)
returns the square root of fi
object a
.
Intermediate quantities are calculated using the fimath
associated
with a
. The numerictype
object
of c
is determined automatically for you using
an internal rule.
c = sqrt(a,T)
returns the square root of fi
object a
with numerictype
object T
.
Intermediate quantities are calculated using the fimath
associated
with a
. See Data Type Propagation Rules.
c = sqrt(a,F)
returns the square root of fi
object a
.
Intermediate quantities are calculated using the fimath
object F
.
The numerictype
object of c
is
determined automatically for you using an internal rule. When a
is
a builtin double
or single
data
type, this syntax is equivalent to c = sqrt(a)
and
the fimath
object F
is ignored.
c = sqrt(a,T,F)
returns the square root fi
object a
with numerictype
object T
.
Intermediate quantities are also calculated using the fimath
object F
.
See Data Type Propagation Rules.
sqrt
does not support complex, negativevalued,
or [Slope Bias] inputs.
For syntaxes where the numerictype
object
of the output is not specified as an input to the sqrt
function,
it is automatically calculated according to the following internal
rule:
$$sig{n}_{c}=sig{n}_{a}$$
$$W{L}_{c}=\mathrm{ceil}(\frac{W{L}_{a}}{2})$$
$$F{L}_{c}=W{L}_{c}\mathrm{ceil}(\frac{W{L}_{a}F{L}_{a}}{2})$$
For syntaxes for which you specify a numerictype
object T
,
the sqrt
function follows the data type propagation
rules listed in the following table. In general, these rules can be
summarized as “floatingpoint data types are propagated.”
This allows you to write code that can be used with both fixedpoint
and floatingpoint inputs.
