Advanced Math Module

The advanced_math module provides distance calculation helper methods.

Distance calculation methods

Advanced Math provides a method that will display the distance, in miles, between two lat/long coordinates.

Usage: getDistance(lat1, lon1, lat2, lon2), where:

• lat1: latitude of the first point
• lon1: longitude of the first point
• lat2: latitude of the second point
• lng2: longitude of the second point

const advancedMath = require('advanced_math');
const distanceInMiles = advancedMath.getDistance(43.7001100, -79.4163000, 37.7749300, -122.4194200);

Degrees to radians

Advanced Math provides a method that will convert degrees to radians.

Usage: deg2rad(deg), where:

• deg: input of degrees

const advancedMath = require('advanced_math');
const radians = advancedMath.deg2rad(30);

Functions support

Functions provides a rich set of tools, and this documentation does not cover all of the potential situations you may encounter. If you need help with a situation not covered by the documentation, please contact PubNub Support
