In general this is not going to work: ``` >>> Mod(1e-30,3) 1.00000000000000e-30 >>> Mod(1e-40,3) 0.0 ``` whereas ``` >>> 1e-40 % 3 9.9999999999999993e-41 ``` Something like this might work when a > b (when a < b the answer is `a`): ``` >>> a,b=pi**3,S(3) >>> (a - round(a/b)*b).n() 1.00627668029982 >>> a.n() % b.n() 1.00627668029982 ``` -- You received this message because you are subscribed to the Google Groups "sympy" group.
