to_rad: Converts degrees to radians

In wolfm4ne/gcd: Great Circle Distance (GCD)

Description

to_rad takes an input of a degree value and will convert it to a radian value by the formula: radian = degree * pi / 180 Typically, this conversion would be in preparation of geocoordinate calculations in which the desired form of the coordinates is radians.

Usage

to_rad(deg)

Arguments

deg	a value in degrees

Examples

# Input list of degree values
# Longitude values range between -180 and +180
deg <- runif(1, -180, 180)
rad <- to_rad(deg)
