I just started writing a program that represents the temperature of an NTC TT102 thermistor. First I tried the famous voltage divider, but I soon found that it is not good. So I decided to uses the NTC formula to get the temperature but it seems not to work. Since the formula results in float numbers, I tried such float variables but still no good results.
What do you think I should do?

The steps I usually use with an NTC thermistor and an Arduino are as follows:
The code I usually use to do the latter is:
R is the resistance, and A, B and C are the coefficients for the NTC Thermistor. (For the thermistor I use these are 0.0015205025, 1.0875337E-4 and 3.2368632E-7 respectively - the datasheet should give you these.)
Which returns the current temperature in Kelvin. Then I have to convert from Kelvin to whatever you want to work in - say for Celcius, just subtract 273.15.
