rounding problem can be corrected by adding the segment of code shown below to the
Calc_Volts
Calc_Volts:
RETURN
v = 5 * adcBits / 255
r = 5 * adcBits // 255
v2 = 100 * r / 255
v3 = 100 * r // 255
v3 = 10 * v3 / 255
IF (v3 >= 5) THEN v2 = v2 + 1
IF (v2 >= 100) THEN
ENDIF
subroutine.
v = v + 1
v2 = 0
