Print function to xbee

Hi,

I am having trouble trying to print the right output for my temperature and pressure values from my xbee. Does anyone know what may be the problem with my code below. By the way the values in my mbed data logger is correct.

snprintf(B, sizeof(B), buf, sizeof(buf), "%X", B ,localtime(&seconds)); snprintf(A, sizeof(A), "Temperature: %d*0.1 Deg C\r Pressure: %d Pa\r Altitude: %f metres\r\n", A ,alt_sensor.get_temperature(),alt_sensor.get_pressure(),alt_sensor.get_altitude_ft());

xbee1.puts(B); xbee1.puts(A);

Values from xbee:

Temperature: 268435948*0.1 Deg C Pressure: 249 Pa Altitude: 112.415822 metres .00:10:04Temperature: 268435948*0.1 Deg C Pressure: 249 Pa Altitude: 112.163348 metres .00:10:06Temperature: 268435948*0.1 Deg C Pressure: 249 Pa Altitude: 113.173281 metres .00:10:08Temperature: 268435948*0.1 Deg C Pressure: 249 Pa Altitude: 112.163348 metres .00:10:10Temperature: 268435948*0.1 Deg C Pressure: 249 Pa Altitude: 112.331663 metres .00:10:12Temperature: 268435948*0.1 Deg C Pressure: 249 Pa Altitude: 112.499981 metres .00:10:13Temperature: 268435948*0.1 Deg C Pressure: 250 Pa Altitude: 112.163348 metres .00:10:15Temperature: 268435948*0.1 Deg C Pressure: 249 Pa Altitude: 112.499981 metres .00:10:17Temperature: 268435948*0.1 Deg C Pressure: 250 Pa Altitude: 112.499981 metres
