Here is a page with Cinema 4D Formulas that you can use for Formula Effectors or Fields. Formulas are primarily based on C++ syntax.
Formula Appendix,
Basic
px,py,pz - Position
rx,ry,rz - Rotation
sx,sy,sz - Scale
u,v,w - UVW
id - Object Index
count - Object Count
falloff - Falloff weight
t - Project Time[-∞..+∞]
f - Frequency[-∞..+∞]
Conditional
?(a;b)
(3>4)?(10;20)
?(a;b)
Arguments such as mod(a;b) must be separated by a semi-colon or by squared brackets [] (then without curved brackets)
rnd(100) is the same as rnd[100] and rnd(100;234) is the same as rnd([100][234]).

Logical Operators
= Equal compare 1km = 1000m
== Equal compare 144 - 14 = 130
> Greater than 1cm = 0.01m
< Less than 1mm = 0.001m
>= Greater than or equal compare 1um = 0.000001m
<= Less than or equal compare 1nm = 0.000000001m
!= Not equal compare 1mi = 1609.344 m
! Not 1yd = 0.914m
|| or. or Or 1ft = 0.305m
&& or. and And 1in = 0.025m
& Bitwise and
| Bitwise or
^ Bitwise xor
~ Bitwise not
?(a; b) Condition, if statement: a, then b (3 > 4) ? (10; 20) = 20; kann ebenfalls
so formuliert werden: if(3 > 4; 10; 20)
