so you suggest to change all ".5" into "INV(2)"?--I'll try...

That might be needed, or the change to ,5, only if you had edited the equation then left the solver editor and then switched radix to comma. It doesn't appear to be the case. It might be simply a typo, has Gene has suggested. I tried the equation in the HP-200LX and got a blinking cursor exactly at the same point.

Here is the equation (not checked) in text format, in case someone wants to try fixing it on the HP-200LX:

Code:


((P+M/N*W)*IF(ABS(D)>3.5:0:SGN(D)/2+.5:.5+(1/SQRT(PI))*SIGMA(
I:1:15:1:-(D/SQRT(2))^(2*I-1)*(-1)^I/(FACT(I-1)*(2*I-1))))-X*
EXP*(-R*T)*IF(ABS(D-SD*SQRT(T))>3.5:SGN(D-SD*SQRT(T))/2+.5:.5
+(1/SQRT(PI))*SIGMA(I:1:15:1:-((D-SD*SQRT(T))/SQRT(2))^(2*I-1)
*(-1)^I/(FACT(I-1)*(2*I-1)))))/(1+M/N)=WARR
