*10^x hiccup on Casio fx-991CW Classwiz
Hi all.

From one of my latest posts on the Casio Calculator Collector Facebook group, there is a peculiar glitch with the x10^x button. The *10^x portion of the typed in value is not connected to its mantissa.

This glitch is evident when a division is part of the mathematical expression input.

For example, take 5/8*10^6. Rather than the expected result of 6.25*10^-7, the result on the 991CW returns 6.25*10^5. Then, as I enter the expression using the x10^x button with parentheses around the 8*10^6 value, such as 5/(8x10^6), the correct answer of 6.25*10^-5 is displayed.
