Nativescript Geosearch Error

I am building an ios version of my android app that uses algolia
I am building the app using the nativescript - angular frameworks

I used the plugin ativeScript-Algolia but everytime I search by aroundLatLng
I get the error

Error : {"status":400,"reason":"Invalid value for "aroundLatLng" parameter, expected float"}

here is the relevant code

//in the constructor of the component
this.client = new Algolia('ddd', 'aaa');
this.index = this.client.initIndex('index');

//inside ngOnInit
let latLng:string = parseFloat(this.lat).toFixed(4) + ',' +
parseFloat(this.lng).toFixed(4);

this.index.search(this.searchTerms , {
aroundLatLng : latLng,
aroundRadius: this.radius

} , (content , err) => {

if(err){
console.log("Error : " + JSON.stringify(err));
}else{
console.log("RESULT IS : " + JSON.stringify(content));
}

});


the result is always the error above ,
how can I resolve this ?
