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

Hy Gerson

Thank you for having re-written the code ..
As you said, substituting the INV(2) or changing radix doesn’t change the problem..the calculator points to the colon to be a point…

The following returns no error, but has yet to be checked:

Code:


((P+M/N*W)*IF(ABS(D)>3.5: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

I have assumed :0 after the first 3.5 shouldn't be there, but I may of course be wrong.

Gerson.
