Figure C.7 Evaluations of And and Or Expressions
Not !
Evaluates as 1 when its argument is false. Otherwise, Not evaluates as 0. When you apply the Not
function, use parentheses where necessary to avoid ambiguity. For example, !(weight==64) can be
either true or false (either 1 or 0), but (!weight)==64 is always false (0) because Not can return only
0 or 1. Expressions such as !(weight==64) can also be entered as weight != 64.
Interpolate
Linearly interpolates the y-value between two points, x1, y1 and x2, y2 that corresponds to the
arguments you give. You can insert additional pairs of x, y arguments with the insert key. Interpolate
finds the pair of x, y points that correspond to the x-value and completes the interpolation.
Step
Is like Interpolate except that it returns the y-value corresponding to the greatest x-value less than or
equal to the x and y arguments. That is, it finds the corresponding y for a given x from a step function
rather than a linear fit between points. Like Interpolate, you can have as many x and y argument pairs as
you want.
C Formula Functions Reference
For
Repeats the statements in the body argument as long as the while condition is true. The init and next
control the iterations.
While
Repeatedly tests the expr condition and executes the body until expr is no longer true.
Break, Continue
Break stops execution of a loop completely and continues to the statement following the loop.
Continue ends the current iteration of a loop and begins the loop at the next iteration.
Both are used in For, While, and For Each Row loops.
