Too complex expressions

define.f ; <- comment this and then you'll get error
Wp=(I*W*(m1+m2)+m1*m2*l*(V1-V2+e*(V1-V2-W*l)))/(I*(m1+m2)+m1*m2*l*l)

Test yourself.
With PB4.0 these expressions run nice when floats or doubles, but it doesn't when running with integers.

Maybe it could use the stack instead of registers?

Nope, for integers PB uses mem positions, but not the stack.

Actually I meant for the temporary storage.

Not the same thing, but also "too complex" for the PB Compiler...

a=Sqr(b<<5)

must be changed to something like

a=b<<5
a=sqr(a)

Here on 4.0 it comes up not able to use << >> | & ! % on floats.
