if any can help i would really appreciate it

here's the problem

A=.082
B=4.15
C=94.2
D=76.76

AA=A*B
BB=C*D
X=-75.12+AA-BB

E=101
CC=E*E
F=EE/301.6
Y=F*703

I read that pic basic pro doesn't support floating point numbers
so how can i approach this problem?

Is there an include file i can include to my problem?
Is there a procedure to follow to calculate my answers
I need to display it with 3 decimals places as well

Any help will be appreciated
thanks for looking
