Advanced Math Module

The advanced_math module is a PubNub Functions utility for distance calculations.

Distance calculation methods

Use getDistance() to return the distance, in miles, between two latitude/longitude 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
• lon2: 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

Use deg2rad() to convert degrees to radians.

Usage: deg2rad(deg) where:

• deg: degrees to convert

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