Finally got FloatExp numbers to work. A FloatExp datatype is a real-valued struct, which contain a floating point number and an extra integer, which holds the exponent.

Then, a real number {mantissa, exponent} can be represented using mantissa×2^exponent.

Using this method, numbers far beyond the range of single and double precision floating point numbers can be represented.

This image is computed using a 32+32 bit floatexp (32 bit mantissa and 32 bit exponent). Plain 32 bit floats are not enough. Of course, perturbation and linear acceleration is also used.
