------
Provides definitions for the ROM/kernal subroutines and utility routines dealing with floating
point variables. This includes ``print_f``, the routine used to print floating point numbers,
``fabs`` to get the absolute value of a floating point number, and some others.
``fabs`` to get the absolute value of a floating point number, and a dozen or so floating point
math routines.
atan(x)
Arctangent.
ceil(x)
Rounds the floating point up to an integer towards positive infinity.
cos(x)
Cosine.
If you want a fast integer cosine, have a look at examples/cx16/sincos.p8
that contains various lookup tables generated by the 64tass assembler.
deg(x)
Radians to degrees.
floor (x)
Rounds the floating point down to an integer towards minus infinity.
ln(x)
Natural logarithm (base e).
log2(x)
Base 2 logarithm.
rad(x)
Degrees to radians.
round(x)
Rounds the floating point to the closest integer.
sin(x)
Sine.
If you want a fast integer sine, have a look at examples/cx16/sincos.p8
that contains various lookup tables generated by the 64tass assembler.
sqrt(x)
Floating point Square root.
To do the reverse, squaring a floating point number, just write ``x*x`` or ``x**2``.

Cosine. (floating point)

Natural logarithm (base e).

rol(x)
Rotate the bits in x (byte or word) one position to the left.
This uses the CPU's rotate semantics: bit 0 will be set to the current value of the Carry flag,

- %import inside a block/subroutine should give compilation error
- pipe operator: allow non-unary function calls in the pipe that specify the other argument(s) in the calls.
- createAssemblyAndAssemble(): make it possible to actually get rid of the VarDecl nodes by fixing the rest of the code mentioned there.
- allow "xxx" * constexpr (where constexpr is not a number literal), now gives expression error not same type

If we can do that why not perhaps also able to inline multi-line subroutines? Why would it be limited to just 1 line? Maybe to protect against code size bloat.
Inlined subroutines cannot contain further nested subroutines!
Once this works, look for library subroutines that should be inlined.
- floats: remove all floating point builtin functions and move them to the floats module instead,
note: first try to move only sin and cos and see if the various examples still work!
