 <input :type="type"

           v-model="inputValue"

           :max-length="maxInputLength"

           :maxlength="maxInputLength"

           :placeholder="rightPlaceholder"

           :class="['input', disabled ? 'input-style-disabled' : '']"

           :disabled="disabled"

           @input="onTextChange"/>

and data is :

 data () {

        return {

            inputValue:'', //input value

        }

    },

    mounted(){

        if(this.value) {

            this.inputValue = this.value;

        }

    },

    methods:{

        formatAmount(value){

            let result;

            if (value.indexOf(".") > 0 && value.length - value.indexOf(".") >= 4){

                result = value.substr(0,value.indexOf('.') + 3);

                // fValue = value.toFixed(2);

                Log.d("formatAmount",result);

            }else {

                result = value;

                Log.d("formatAmount else",result);

            }

            return result;

        },

        onTextChange() {

            setTimeout(() => {

                this.inputValue = this.formatAmount(this.inputValue);

                this.$emit("onTextChange",this.inputValue);

            }, 10);

        }

    }

You can use array split on (.) and then check arr[1].length<=2 and arr[0].length <=6.or use regex /^d+(.d{1,2})?$/ for 2 radix point;
