cirq_google.serialization.arg_func_langs.float_arg_from_proto

Extracts a python value from an argument value proto.

cirq_google.serialization.arg_func_langs.float_arg_from_proto(
    arg_proto: cirq_google.api.v2.program_pb2.FloatArg,
    *,
    arg_function_language: str,
    required_arg_name: Optional[str] = None
) -> Optional[FLOAT_ARG_LIKE]

This function handles FloatArg protos, that are required to be floats or symbolic expressions.

Args
`arg_proto`	The proto containing a serialized value.
`arg_function_language`	The `arg_function_language` field from `Program.Language`.
`required_arg_name`	If set to `None`, the method will return `None` when given an unset proto value. If set to a string, the method will instead raise an error complaining that the value is missing in that situation.

Returns
The deserialized value, or else None if there was no set value and `required_arg_name` was set to `None`.

Raises
`ValueError`	If the float arg proto is invalid.
