Wrong solution to an operation in the console

Description

What steps will reproduce the problem?

I was doing simple calculations and I realized an operation I wrote in the console yielded a wrong result.

I needed to check the output of operation 47. As it was not giving the same result of my C code I needed to check I went trhough the fidderent step of my calculation and realized the same operation could yield 2 different results. I do not know how it is possible. The correct solution to 47 was first obtained at 54. Then touching the arrow keyboard touch to come back to operation 47 still give the same wrong result...
