/*
|
|
Convert integer to its string representation in given scale of notation.
|
|
|
|
SYNOPSIS
|
|
int2str()
|
|
val - value to convert
|
|
dst - points to buffer where string representation should be stored
|
|
radix - radix of scale of notation
|
|
upcase - set to 1 if we should use upper-case digits
|
|
|
|
DESCRIPTION
|
|
Converts the (long) integer value to its character form and moves it to
|
|
the destination buffer followed by a terminating NUL.
|
|
If radix is -2..-36, val is taken to be SIGNED, if radix is 2..36, val is
|
|
taken to be UNSIGNED. That is, val is signed if and only if radix is.
|
|
All other radixes treated as bad and nothing will be changed in this case.
|
|
|
|
For conversion to decimal representation (radix is -10 or 10) one can use
|
|
optimized int10_to_str() function.
|
|
|
|
RETURN VALUE
|
|
Pointer to ending NUL character or NullS if radix is bad.

The slightly contorted code which follows is due to the fact that

few machines directly support unsigned long / and %. Certainly

the VAX C compiler generates a subroutine call. In the interests

of efficiency (hollow laugh) I let this happen for the first digit

only; after that "val" will be in range so that signed integer
|
|
division will do. Sorry 'bout that. CHECK THE CODE PRODUCED BY
|
|
YOUR C COMPILER. The first % and / should be unsigned, the second
|
|
% and / signed, but C compilers tend to be extraordinarily
|
|
sensitive to minor details of style. This works on a VAX, that's

all I claim for it.
