format.fix

Format to a fixed format representation

Description

formatFix formats to fixed point number format. It 'writes' x with sign (" " or "-"), with before decimals before the "." and with after decimals after the ".". If after == 0 then the "." will be omitted.
There will always be at least one decimal digit before the "."
If before is too small to represent x: if extend==TRUE, the string will be extended, else a string consisting of "*" of length before+after will be given.
If abs(x) >= 10^8, values very near 10^k cannot be represented exactly, so the normal format will be used.
Names are retained. The vector or array structure will be preserved

Usage

formatFix(x,after=2,before=1,extend=TRUE)

Arguments

`x`	Real,the number to be represented.
`after`	integer, The number of decimals after ".".
`before`	Integer, the minimum number of decimals before ".".
`extend`	Logical, extend string if necessary.

Value

The string representing the fixed point format of x.
