# Convert radians to degrees and degrees to radians.
#
# Uses Ruby's built‑in Math module:
# - Math::PI provides a precise value for π.
# - The conversion formulas follow the standard mathematical relationships:
# degrees = radians * (180 / Math::PI)
# radians = degrees * (Math::PI / 180)
#
# The program demonstrates clear structure:
# - Small, focused functions
# - Descriptive names
# - Comments explaining intent
#
# Convert radians to degrees.
# Multiplies the input by the ratio between degrees and radians.
def to_degrees(radians)
radians * (180.0 / Math::PI)
end
# Convert degrees to radians.
# Multiplies the input by the ratio between radians and degrees.
def to_radians(degrees)
degrees * (Math::PI / 180.0)
end

# Example values
