I am calculating a fraction based on the payments made in four years and I wish to put a cap on my fraction such that it can only be between -1 and 1. Subsequently I'd like to make the following fractions 0 if the cap is maxxed out - an example would be:
data want;
input payment1 payment2 payment3 payment4 fraction1 fraction2 fraction3;
datalines;
100 25 25 25 0.25 0.25 0.25
150 50 50 50 0.33 0.33 0.33
50 10 10 10 0.2 0.2 0.2
10 50 60 70 1 0 0
;
run;
I've been looking at the ceiling function with the following code
data want2;
set want;
array fraction(3) fraction1 - fraction3;
array payment(4) payment1 - payment4;
do i = 2 to 4;
fraction(i-1) = payment(i)/payment(1);
end;
run;
data want3;
set want2;
array fraction(3) fraction1 - fraction3;
array fract(3) fract1-fract3;
do i = 1 to 3;
fract = ceil (fraction,1);
end;
drop i;
run;
but I am getting this error
ERROR 72-185: The CEIL function call has too many arguments.
So in all i'm looking for a way to calculate the fraction of the payments and then make a ceiling at one, then once the ceiling is hit, the subsequent fractions must be zero (which could be done I suppose by just doing an IF-THEN)
