    CCS trigonometric calculation

    hi when i put the value 0x7543 in an "int16", in RAM that is shown as it is. But when i put 0x7543 in float, it gives an other 32 bit value in RAM which is "866A8D" what does it mean? an i want to calculate trigonometry like cos45*sin90... etc. (in degrees) how can i do it ? urgent help is needed
