Method: Joules.density

Defined in:
lib/joules/density.rb

.density(mass, volume) ⇒ Float

Calculates the density given mass and volume.

Examples:

Joules.density(8.96, 0.002) #=> 4480.0

Parameters:

  • mass (Int, Float) —

    mass >= 0; mass is in kilograms

  • volume (Int, Float) —

    volume > 0; volume is in metres cubed

Returns:

  • (Float) —

    return value >= 0; return value is in kilograms per metre cubed

Raises:

  • (ZeroDivisionError) —

    if volume = 0
