In general, the demand for a good is said to be inelastic (or relatively inelastic) when the PED is less than one (in absolute value): that is, changes in price have a relatively small effect on the quantity of the good demanded.
This is known as being perfectly inelastic. Therefore, inelastic demand occurs when the ratio of quantity demanded to price is between zero (perfectly inelastic) and one (unit elastic). Here's a real life example using beef prices in 2014. Prices rose 28%, but demand only fell 14.9%.
