How can we produce the number x.y, where x and y are the two arguments or a function?

I wish this helpful for you For positive values of reasonable magnitude, subject to floating-point rounding:
code :
float CombineToFloat(int Num1, int Num2)
{
    float PowerOf10 = 1;
    while (PowerOf10 <= Num2)
        PowerOf10 *= 10;
    return Num1 + Num2/PowerOf10;
}
float CombineToFloat(int Num1, int Num2)
{
    float PowerOf16 = 1;
    while (PowerOf16 <= Num2)
        PowerOf16 *= 0x10;
    return Num1 + Num2/PowerOf16;
}

How to count the number of arguments passed to a function that accepts a variable number of arguments?

around this issue You can't. You have to manage for the caller to indicate the number of arguments somehow. You can:
Pass the number of arguments as the first variable Require the last variable argument to be null, zero or whatever Have the first argument describe what is expected (eg. the printf format string dictates what arguments should follow)

recursive function with variable number of arguments - how to pass left arguments?

seems to work fine What's wrong with just doing (demo)
code :
foreach ($months as $month) {
    foreach ($month as $letter => $value) {
        if (isset($months['all'][$letter])) {
            $months['all'][$letter] += $value;
        } else {
            $months['all'][$letter] = $value;
        }
    }
}
print_r($months['all']);
$iterator = new RecursiveIteratorIterator(new RecursiveArrayIterator($months));
foreach ($iterator as $letter => $value) {
    isset($months['all'][$letter])
        ? $months['all'][$letter] += $value
        : $months['all'][$letter] = $value;
}
print_r($months['all']);

Pass a function with undetermined number of arguments and call it with the variadic arguments

like below fixes the issue You can't expand a va_list into separate arguments. The function you want to call have to be able to take a va_list as argument. See e.g. printf versus vprintf.

Is it possible to use tag function arguments to produce the exact same sequence of literals and placeholders?

like below fixes the issue A template literal always starts and ends with a character component, which alternate with substitutions. It always has one more string part than substitutions. A placeholder can never come "first" - it might come after an empty string, though:
code :
const say = 42;
tag `{say} it is`;
function tag(strings, ...placements) {
    console.assert(strings[0] === "")
    console.assert(strings[1] === " it is");
    console.assert(placments[0] === 42);
    console.assert(strings.length == placements.length+1);
}

PLS-00306: wrong number or types of arguments tips on function with "variable" number of arguments

I hope this helps you . You call st_transform with shape which is st_geometry and srid which is INTEGER. Oracle says there is no matching definition of ST_TRANSFORM_F with types (st_geometry, integer). Or more precisely Oracle cannot convert parameters with actual types (st_geometry, integer) to any of existing definition of ST_TRANSFORM_F.
Quick demonstration.
code :
SQL> create or replace function ST_TRANSFORM_F(i in integer) return integer
  2  as begin return 1; end;
  3  /

Function created.

SQL> create or replace function f(p in sys.odcinumberlist) return integer as
  2  begin return ST_TRANSFORM_F(p); end;
  3  /

Warning: Function created with compilation errors.

SQL> sho err

SQL> create or replace function f(p in number) return integer as
  2  begin return ST_TRANSFORM_F(p); end;
  3  /

Function created.
