number base conversion for hp17b/17bii

[Don Shepherd]

OK, you've got your old 17b or 17bii you use for all your financial needs, but now you need something to do number base conversions. There is no need to go to a scientific model, the solver is your friend.

B1 = old base (2-10)
B2 = new base (2-10)
N = number to convert
ANS = solve for this

Either B1 or B2 must be 10.

BC:ANS=\(\Sigma\)(I:0:LOG(N)\(\div\)LOG(B2):1:MOD(N:B2)\(\times\)B1^I+0\(\times\)L(N:IDIV(N:B2))​)
