int2: convert integers, string to integer vector

In cwhmisc: Miscellaneous Functions for Math, Plotting, Printing, Statistics, Strings, and Tools

Description

Functions for conversion to string representation of integers to arbitrary bases

Usage

  NdM( x, B=10 )
  int2ASCII( n)
  int2B( n, B=10, space, plus=lead, lead="",just=c("left","right","center","none") )
  int2Oct( n )
  int2Hex( n )
  strRound( str, digits = getOption("digits"), B=10)

Arguments

str	String representing a real
n	Integer vector
B	1 < integer < 17, base of representation
space	Integer, space for conversion
plus	string for signifying positive values, usually "" or "+"
lead	string for insertion between sign and first significant digit, usually "" or "0"
just	String for choosing kind of justification within 'space', partial matching allowed
x	Vector of reals
digits	no. of digits for roeunding

Details

int2Oct Convert integer to octal representation.
int2Hex Convert integer to hex representation

Value

NdM maximum number of decimal places needed for trunc(x)
int2ASCII,int2B,int2Oct,int2Hex vector of strings represented by 'n'
strRound real, represented by x

Examples

  NdM(10^(1:4)) # 5
  int2ASCII(1:255)[121:129] # "x" "y" "z" "{" "|" "}" "~" "\177" "\200"
  int2B(1:50,2) # all of same length
  int2B(1:50*(-1)^(1:50),just="r") # left flush
  unlist(sapply(1:50,int2B,2,just="l")[1,] ) # individual lengths
  unlist(sapply(1:50,int2B,7)[1,] ) # individual lengths
  unlist(sapply(1:50,int2B)[1,] )
  unlist(sapply(1:50,int2Oct)[1,] )
  unlist(sapply(1:50,int2Hex)[1,] )
  strRound(pi*10^4,0)/10^4 == strRound(pi,4) # TRUE
