Temprature conversion --- C to F

[Normnet]

F = C * 9 'DO LESS THE BIT.7 NEG/POS BIT
F = F / 5
IF T_MSB.7 = 1 THEN 'if the sign bit is "1", is minus C
F = 32 - F
else
F = 32 + F
ENDIF

Try again:
F = C * 9 'DO LESS THE NEG/POS BIT
F = F / 5
IF T_MSB.7 = 1 THEN 'if the sign bit is "1", is minus C
F = F - 32
else
F = F + 32
ENDIF
