Convert fi object to signed 64-bit
integer
c = int64(a)
c = int64(a) returns the built-in int64 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 int64.
This example shows the int64 values of a
fi object.
a = fi([-pi 0.1 pi],1,64); c = int64(a) c = -3 0 3
