Examples of com.lowagie.text.pdf.PdfNumber

com.lowagie.text.pdf.PdfNumber
PdfNumber provides two types of numbers, integer and real.
Integers may be specified by signed or unsigned constants. Reals may only be in decimal format.
This object is described in the 'Portable Document Format Reference Manual version 1.7' section 3.3.2 (page 52-53). @see PdfObject @see BadPdfFormatException
