== _Numbers can be expressed as integers or floating point values_ In [[awk]], numbers can be expressed as decimal [integer]]s or as [[floating point]] values. == _Numbers should be specified in decimal_ The [[awk]] programming language does not provide facilities for specifying numbers in non [[decimal]] bases. However numerical values in [[output]] can be formatted into [[octal]] or [[hexadecimal]]. == _Positive and negative numbers_ Negative numbers in awk must be prefixed with a minus numbersign operator: number = -5 It is also possible to use the plus symbol as a unary numbersign operator to prefix positive numbers. However, this form is generally not required, because numbers are positive by default: number = +6 # 6 is positive
