Functions
double	no_os_typek_temp_to_voltage (double temp_celsius)
	ITS-90 Type K thermocouple forward polynomial. Converts temperature (°C) to equivalent EMF voltage (mV). Valid for 0°C to 1372°C range.
double	no_os_typek_voltage_to_temp (double voltage_mv)
	ITS-90 Type K thermocouple inverse polynomial. Converts thermocouple voltage (mV) to temperature (°C), -200°C to 500°C. Uses separate polynomial ranges for negative and positive voltages.
