Convert fi object to signed 32-bit integer
c = int32(a)
c = int32(a) returns the built-in int32 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 int32.
This example shows the int32 values of a fi object.
a = fi([-pi 0.1 pi],1,32); c = int32(a) c = -3 0 3
