wms url petition does not work with coordinates with decimals

I have this to get the point when the user clicks on a map using betterWms plugin

getFeatureInfoUrl: function (latlng) 
  {
    // Construct a GetFeatureInfo request URL given a point
    var point = this._map.latLngToContainerPoint(latlng, this._map.getZoom()), size = this._map.getSize(),
    params = {
          request: 'GetFeatureInfo',
          service: 'WMS',
          srs: 'EPSG:4326',
          styles: this.wmsParams.styles,
          transparent: this.wmsParams.transparent,
          version: this.wmsParams.version,      
          format: this.wmsParams.format,
          bbox: this._map.getBounds().toBBoxString(),
          height: size.y,
          width: size.x,
          layers: this.wmsParams.layers,
          query_layers: this.wmsParams.layers,
          info_format: 'application/json'
    };
    
    params[params.version === '1.3.0' ? 'i' : 'x'] = point.x;
    params[params.version === '1.3.0' ? 'j' : 'y'] = point.y;
    
    console.log(point);
    var url = this._url + L.Util.getParamString(params, this._url, true);

The url is valid when the clicked point has no decimals, so by just removing them works, but I need to use decimals.

I try changing the url decimal to %2E, %2C, and also for comma and point but neither of this solutions works, the only way of having a valid url is by removing the decimals.

This petition is being send to geoserver, the data is a shapefile and it displays in the correct places, the src is the same in geoserver and in the code (EPSG:4326).

I also try to change in the layer the decimals in the WFS section to 50 decimals but the petition is wms so I don’t know if this will do something or not.

Could you tell what could I do please?
