Looking for help on understanding the notation of filenames like "Mobilenet_V1_1.0_224_quant.tflite"

I’m looking at running some models from https://www.tensorflow.org/lite/guide/hosted_models

The model filename is something like `Mobilenet_V1_1.0_224_quant.tflite`

I understand that 224 is the input size but I’m not sure what the 1.0 represents. It would be useful if someone can tell me what the 1.0 means. Feel free to link some docs that would give me insight if you find that easier 🙂

Thanks in advance, really appreciate it.
