SYNOPSIS

logical function codebase(in_base10,out_base,answer,uc)

   integer,intent(in)           :: in_base10
   integer,intent(in)           :: out_base
   character(len=*),intent(out) :: answer
   logical,intent(in),optional  :: uc

DESCRIPTION

Convert a number from base 10 to base OUT_BASE. The function returns [char46]FALSE. if OUT_BASE is not in the range [2..36] or if number IN_BASE10 is too big.

The letters A,B,...,Z represent 10,11,...,36 in the base > 10.

OPTIONS

in_base10
	whole number to convert to an alternate base
out_base
	the desired base of the output
answer	the input value converted to a string representing the original number IN_BASE10 in base OUT_BASE.
uc	returned letters are uppercase if .true., lowercase if .false.

RETURNS

Returns .true. if no error occurred, else returns .false. .

EXAMPLES

Sample program:

   program demo_codebase
   use M_strings, only : codebase
   implicit none
   character(len=20) :: answer
   integer           :: i, j
   logical           :: ierr
   do j=1,100
      do i=2,36
         ierr=codebase(j,i,answer)
         write(*,*)’VALUE=’,j,’ BASE=’,i,’ ANSWER=’,answer
      enddo
   enddo
   end program demo_codebase
