formatFix: 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

The number to be represented.

after

The number of decimals after ".".

before

The minimum number of decimals before ".".

extend

Extend string if necessary.

Value

The string representing the fixed point format of x.

xx    <- c(0.001,92,exp(1),1000*pi)
formatFix(c(-rev(xxbig),-rev(xx),0,NA,xx,xxbig),0,3)
