I don't get what is happening here. I used this exact code for another algorithm and it works but here i only get large negative numbers for an input, what gives?

My output is:

floatArray[0] is -107374176.000000

floatArray[1] is -107374176.000000

floatArray[2] is -107374176.000000

floatArray[3] is -107374176.000000

floatArray[4] is -107374176.000000

floatArray[5] is -107374176.000000

floatArray[0] is -107374176.000000

floatArray[1] is -107374176.000000

floatArray[2] is -107374176.000000

floatArray[3] is -107374176.000000

floatArray[4] is -107374176.000000

floatArray[5] is -107374176.000000
