nextpow2
Syntax
Description
Examples
Next Power of 2 of fi
Object
Define a fi
object and calculate the exponent for
the next higher power of 2.
N = fi(1000,1,18,2); P = nextpow2(N)
P = 10 DataTypeMode: Fixed-point: binary point scaling Signedness: Signed WordLength: 6 FractionLength: 0
Next Power of 2 of fi
Values
Define a vector of fi
values and calculate the
exponents for the next power of 2 higher than those values.
N = fi([1 -2 3 -4 5 9 519],1,16,3,2); P = nextpow2(N)
P = 1 0 1 2 3 3 10 DataTypeMode: Fixed-point: binary point scaling Signedness: Unsigned WordLength: 5 FractionLength: 0
Input Arguments
N
— Input values
scalar | vector | N-dimensional array
Input values, specified as a real-valued scalar, vector, or N-dimensional array.
Data Types: fi
Output Arguments
P
— Exponent of next higher power of 2
scalar | vector | N-dimensional array
Exponent of next higher power of 2, returned as a scalar, vector, or N-dimensional array.
The output is returned as an unsigned fi
object with binary-point
scaling, a fraction length of zero, and the smallest word length which can represent the
value of the largest returned exponent.
