Data of type double cannot be directly compared with =

You need to compare in terms of packaging types:

/ / if D1 and D2 are double types

If (Double.doubleToLongBits (D1) = = Double.doubleToLongBits (D2))

/ / F1 and f2 are D2 and float types

If (Float.floatToIntBits (F1) = = Float.floatToIntBits (f2))

These are the native methods.

Public static native long doubleToRawLongBits (double var0)

Public static native double longBitsToDouble (long var0)
