SIN
returns the 8-bit sine of a value. The result is in two’s complement form (i.e. -
127 to 127). It uses a quarter-wave lookup table to find the result. SIN starts with a
value in binary radians, 0 to 255, as opposed to the usual 0 to 359 degrees.
I assume that the F2/180 term below is an attempt to convert B2 (35.110765 degrees ) to radians with increased resolution
SİN(B2*F2/180)
it won't work
for a start pbp sin function wants the input to be a Brad and the result will be a signed byte .
the best you can get with pbp is :-
all vars here are words
B0=351 ; 35.1 deg * 10 ie degrees x 10
B1=B0 */ 182 ; convert to brad ( B0 * 255)/360
B1=(B1+5)/10 ; scale back to degrees x 1 ( with rounding )
B2= sin(B1) ; sin 35.1 = 0.575 === pbp sin(25)=73
serout2 PORTA.0,84, ["brad 35.1 =",# B1,13,10 ] ;===== 25
serout2 PORTA.0,84, ["sin 35.1 =",# B2,13,10 ] ;==== 73
73 ====== 73/127 ===== 0.5748

its more likely you will get a better result from the forum if you explain what you are trying to achieve .
along with your attempted code

btw there is no acos function in pbp
