Dear all,
I am staring already for half an hour at the following. This piece of
code:
reset()
print 'Loop 1:'
B=-2
for A in range(-3,-1):
C=-A*B/(A+B)
print "A:",A,"B:",B,"C:",C,"A*B+C*(A+B)=",A*B+C*(A+B)
print 'Loop 2:'
for A in range(-3,-1):
for B in range(-3,-1):
C=-A*B/(A+B)
print "A:",A,"B:",B,"C:",C,"A*B+C*(A+B)=",A*B+C*(A+B)
should in both loops (obviously) always assign that value to C such
that A*B+C*(A+B) is 0. This indeed happens in the first loop, but not
in the second. Here is the output (Kubuntu 11.04, Sage v. 4.6.2):
Loop 1:
A: -3 B: -2 C: 6/5 A*B+C*(A+B)= 0
A: -2 B: -2 C: 1 A*B+C*(A+B)= 0
Loop 2:
A: -3 B: -3 C: 1 A*B+C*(A+B)= 3
A: -3 B: -2 C: 1 A*B+C*(A+B)= 1
A: -2 B: -3 C: 1 A*B+C*(A+B)= 1
A: -2 B: -2 C: 1 A*B+C*(A+B)= 0
What is happening here? I am sorry for obviously completely
overlooking something trivial...
Many thanks for your help, Kees
