Analog Clock

This is my attempt to port the analogClock.aec from Linux, Windows and FreeDOS to WebAssembly, using my new compiler.
This only works in very modern browsers. I'm not too interested in targeting archaic browsers here. This only works in Firefox 62 and newer or Chrome 69 and newer (that is, those that support WebAssembly.Global). After a few years (if not months), all JavaScript environments will become as capable as they are, rather than like Internet Explorer.

AEC program output:

You can see the source code of the AEC program here. I had to implement custom math functions, because WebAssembly has no fsin and similar instructions which x86 assembly has.

UPDATE on 18/01/2023: If you want to try out this program in NodeJS, you can use the following shell script I've written:

if [ $(command -v git > /dev/null 2>&1 ; echo $?) -eq 0 ]
then
  git clone https://github.com/FlatAssembler/AECforWebAssembly.git
  cd AECforWebAssembly
elif [ $(command -v wget > /dev/null 2>&1 ; echo $?) -eq 0 ]
then
  mkdir AECforWebAssembly
  cd AECforWebAssembly
  wget https://github.com/FlatAssembler/AECforWebAssembly/archive/refs/heads/master.zip
  unzip master.zip
  cd AECforWebAssembly-master
else
  mkdir AECforWebAssembly
  cd AECforWebAssembly
  curl -o AECforWebAssembly.zip -L https://github.com/FlatAssembler/AECforWebAssembly/archive/refs/heads/master.zip # Without the "-L", "curl" will store HTTP Response headers of redirects to the ZIP file instead of the actual ZIP file.
  unzip AECforWebAssembly.zip
  cd AECforWebAssembly-master
fi
if [ $(command -v g++ > /dev/null 2>&1 ; echo $?) -eq 0 ]
then
  g++ -std=c++11 -o aec AECforWebAssembly.cpp # "-std=c++11" should not be necessary for newer versions of "g++". Let me know if it is, as that probably means I disobeyed some new C++ standard (say, C++23).
else
  clang++ -o aec AECforWebAssembly.cpp
fi
cd analogClock
../aec analogClock.aec
npx -p wabt wat2wasm analogClock.wat
if [ "$OS" = "Windows_NT" ] # https://stackoverflow.com/a/75125384/8902065
                            # https://www.reddit.com/r/bash/comments/10cip05/comment/j4h9f0x/?utm_source=share&utm_medium=web2x&context=3
then
  node_version=$(node.exe -v)
else # We are presumably running on an UNIX-like system, where storing output of some program into a variable works as expected.
  node_version=$(node -v)
fi
# "node -v" outputs version in the format "v18.12.1"
node_version=${node_version:1} # Remove 'v' at the beginning
node_version=${node_version%\.*} # Remove trailing ".*".
node_version=${node_version%\.*} # Remove trailing ".*".
node_version=$(($node_version)) # Convert the NodeJS version number from a string to an integer.
if [ $node_version -lt 11 ]
then
  echo "NodeJS version is lower than 11 (it is $node_version), you will probably run into trouble!"
fi
