julia> BigFloat(1/26) 0.0384615384615384636735058165868395008146762847900390625 julia> 1/26 0.038461538461538464 In fact, 1/26=0.0384615[384615]… 384615 as a decimal cycle section. So I doubt the value of BigFloat(1/26) and 1/26 giving by Julia are not correct. What happened？

[image] a-boy: julia> BigFloat(1/26) julia> BigFloat(1)/BigFloat(26) 0.03846153846153846153846153846153846153846153846153846153846153846153846153846162 The code BigFloat(1/26) first computes 1/26 which becomes a Float64 and then converts that to a BigFloat.

Why does Julia say 1/26=0.038461538461538464
