ENG button in Casio calculator

[cclinus]

Hi,

First, I don't want the calculator to display every number in engineering format. I just want it to display Eng format when I need.

Second, you don't need to set it back to standard format after use.

Third, for example, 0.001, the calculator is always display "1E-3" in Eng format. But , sometimes, I want it display in "1000E-6". That's why I need ENG button.

Thanks!
