It depends whether you want 00-99 or 1-100. Eclipse Phase, for example, uses 00-99 so that criticals (which are on doubles) are evenly distributed. It compensates by making success only on a roll strictly less than, not less-than-or-equal-to, your target.
Just to clarify, that’s usually 2 d10s. One with the decimals (10,20…90) like you said, and another with the units. (1,2…9).
Also, zeroes in both dice are considered 100.
On another note, there are actually single dice that go from 1 to 100, but they’re more of a novelty thing and don’t roll super well.
