Deleting 5 after entering say 500 causes everything to be deleted about ngx-mask

[smartredfox]

It looks like the check to see if a decimal separator needs to be added needs an additional check to see if it's a zero, otherwise it adds a second decimal - this then causes issues when the later formatters run. The same issue occurs for any number where the next digit is a zero (505,000 for example becomes 0.50 when you delete the first 5).

This seems to fix it:

                if (inputValue[0] === "0" /* MaskExpression.NUMBER_ZERO */ &&
                    inputValue[1] !== "0" && /*This seems to fix it */
                    inputValue[1] !== decimalMarker &&
                    inputValue[1] !== this.thousandSeparator) {
                    // eslint-disable-next-line no-param-reassign
                    inputValue =
                        inputValue.length > 1
                            ? inputValue.slice(0, 1) +
                                decimalMarker +
                                inputValue.slice(1, inputValue.length + 1)
                            : inputValue;
                    this.plusOnePosition = true;
                }
