Convert fi object to unsigned 64-bit
integer
c = uint64(a)
c = uint64(a) returns the built-in uint64 value
of fi object a, based on its
real world value. If necessary, the data is rounded-to-nearest and
saturated to fit into an uint64.
This example shows the uint64 values of a
fi object.
a = fi([-pi 0.5 pi],0,64); c = uint64(a) c = 0 1 3
