Remarks

A PdfNumber -class is the PDF-equivalent of a Double -object.

PDF provides two types of numeric objects: integer and real. Integer objects represent mathematical integers. Real objects represent mathematical real numbers. The range and precision of numbers may be limited by the internal representations used in the computer on which the PDF processor is running. An integer shall be written as one or more decimal digits optionally preceded by a sign. The value shall be interpreted as a signed decimal integer and shall be converted to an integer object. A real value shall be written as one or more decimal digits with an optional sign and a leading, trailing, or embedded period (decimal point).
