π = 22/7 - ∫(0,1,X^4*(1-X)^4/(1+X^2),X)

I entered this into my Sharp Writeview EL-W506T and got the result of 'π'
Admittedly I expected the numerical value of π

Same on the CASIO fx-991 LA X CLASSWIZ.
There’s a setting for numerical values:

SHIFT SETUP
1: Input/Output
2: MathI/DecimalO

Regardless the setting, the S<=>D key cycles between both formats.

On the EL-W506T you can try the ->CHANGE<- key.
