convert error: 'Int' to 'IntLiteral' trying to implement the FloatLiteral.round(ndigits) method

I'm trying to contribute implementing the FloatLiteral.round() method with the current implementation:

    @always_inline("nodebug")
    fn __round__(self, ndigits: IntLiteral = 0) -> Self:
        """Return the rounded value of the FloatLiteral.

        Args:
            ndigits: The number of digits to round to. Defaults to 0.
        Returns:
            The rounded value.
        """
        # Handle special values first.
        if not self._is_normal():
            return self

        var pow: IntLiteral = 10 ** ndigits
        var to_round: Self = self * Self(pow)
        var truncated: IntLiteral = to_round.__int_literal__()
        var result: Self
        if self.__abs__() - Self(truncated).__abs__() < 0.5:
            result = Self(truncated)
        elif self > 0:
            result = Self(truncated + 1)
        else:
            result = Self(truncated - 1)
        if ndigits > 0:
            result = result / (Self(10.0) ** ndigits)
        return result

    @always_inline("nodebug")
    fn __round__(self, ndigits: IntLiteral = 0) -> Self:
        """Return the rounded value of the FloatLiteral.

        Args:
            ndigits: The number of digits to round to. Defaults to 0.
        Returns:
            The rounded value.
        """
        # Handle special values first.
        if not self._is_normal():
            return self

        var pow: IntLiteral = 10 ** ndigits
        var to_round: Self = self * Self(pow)
        var truncated: IntLiteral = to_round.__int_literal__()
        var result: Self
        if self.__abs__() - Self(truncated).__abs__() < 0.5:
            result = Self(truncated)
        elif self > 0:
            result = Self(truncated + 1)
        else:
            result = Self(truncated - 1)
        if ndigits > 0:
            result = result / (Self(10.0) ** ndigits)
        return result

But I'm receiving the error: cannot implicitly convert 'Int' value to 'IntLiteral' in 'var' initializer in the var pow: IntLiteral = 10 ** ndigits line If I change the type to from IntLiteral to Int this will move the error to the following line, the to_round declaration .

Now I'm not sure if it's a compiler issue, as I also found an error with this minimalistic example:

fn get_intliteral() -> IntLiteral:
    return IntLiteral(10 ** 2)

fn get_intliteral() -> IntLiteral:
    return IntLiteral(10 ** 2)

I'm getting error: no matching function in initialization and in the error details candidate not viable: argument #0 cannot be converted from 'Int' to '!kgen.int_literal'
