You can not find a variable was over flown but you can avoid it, if that was your series problem then do like this

Code C - [expand]
1 2 3 4 5 6	double temp; if(temp = ((y)someval+z) > MAX_FLOAT_VALUE) of = 1; else x=(y)someval+z;

better if you have doubt that its going to ovrflow then you shd use a double type....
