Numerical Calculations
# You cannot use a differential, quadratic
differential, integration, Σ , maximum/minimum
value, Solve, RndFix or log ab calculation
expression inside of a Σ calculation term.
# Make sure that the value used as the fi nal term
β
is greater than the value used as the initial
term
α
. Otherwise, an error will occur.
# To interrupt an ongoing Σ calculation (indicated
when the cursor is not on the display), press the
