wrong positive and negative voltages on lcd 20x4

[richard]

VALOR1=B1/9
VALOR2=B2/12

b1 = 329 , b1/9 =35 target is 12.2 why divide by 9 ?
b2 = 360 , b2/12=30 target is 12.3 why divide by 12 ?


to get more resolution
dummy = b1*100
VALOR = div32 26
result = 1226 ie 12.26 *100

an even more accurate result is possible using */

In my previous code I had many errors due to the mathematical equations and I was able to partially correct these errors using the fp2032.bas library.
even the code continues with the errors in mathematical equations, for that reason I went to the lighthouse to see if they could help correct the code, thanks
