vm_set_obaseThe pre-defined function vm_set_obase sets the output base in
the underlying VM. It has the following prototype:
fun vm_set_obase = (int<32> obase) void:
Where obase is the output base to set. The base must be one of
2 (for binary), 8 (for octal), 10 (for decimal) or 16 (for
hexadecimal). If the provided base is not contained in that set,
vm_set_obase raises E_inval.
