Most significant bit
c = getmsb(a)
c = getmsb(a) returns the value of the most significant bit in a as a u1,0.
a can be a scalar fi object or a vector fi object.
getmsb only supports fi objects with fixed-point data types.
The following example uses getmsb to find the most significant bit in the fi object a.
a = fi(-26, 1, 6, 0); c = getmsb(a) c = 1 DataTypeMode: Fixed-point: binary point scaling Signedness: Unsigned WordLength: 1 FractionLength: 0 >>
You can verify that the most significant bit in the fi object a is 1 by looking at the binary representation of a.
