diameter -- diameter of an interval

Description

Returns the diameter (the difference between the endpoints) of the input interval.

i1 : interval (2, 7)

o1 = [2,7]

o1 : RRi (of precision 53)
 
i2 : diameter oo

o2 = 5

o2 : RR (of precision 53)

For a complex interval, the length of the diagonal in the complex plane is returned.

i3 : interval (0, 3 + 4*ii)

o3 = [0,3]+[0,4]*ii

o3 : CCi (of precision 53)
 
i4 : diameter oo

o4 = 5

o4 : RR (of precision 53)

Ways to use diameter:

  • diameter(CCi)
  • diameter(RRi)
