Moving from 200LX SOLVER to SAGEmath *)

[Peter A. Gebhardt]

Dear fellow SOLVER users,

any idea, how to move (solve!) a construct like

Code:

if(S(SvNow)
:inv(1+if(Save1=0:%AgSvTarget:%AgSvNow)/100)
:inv(1+%AgSvNow/100)
)

to (in) SAGEmath?

Best regards

Answering myself - Python's identation and variable naming were the stoppers ;-)

Not being allowed to use the % character in variable names, makes developing self-documenting code for financial tasks in SAGEmath a bit harder too.

(print statements added to visualize decision tree)

Code:

var ('S, Save1, _AgSvTarget, _AgSvNow')
_AgSvTarget=5; _AgSvNow=3.0; S=1; Save1=0.0

if S == 1: 
    if Save1 == 0:
        print 1,  1/(1 + _AgSvTarget/100)
    else:
        print 2,  1/(1 + _AgSvNow/100)        
else:    
    print 3,  1/(1 + _AgSvNow/100)

Best regards

And I was thinking the problem is the S (solving for) function.
