,y
n
point pairs
are plotted and
connected by straight
lines
MIN(x,y) minimum of x and
y
MAX(x,y) maximum of x and
y
LIMIT(x,min,max) min if x < min
max if x > max
else x
SGN(x) +1 if x > 0
0 if x = 0
-1 if x < 0
STP(x) 1 if x > 0
0 otherwise
which is used to
suppress a value until a
given amount of time
has passed
IF(t,x,y) x if t is true
y otherwise
where t is a relational
expression using the
relational operators
