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
