No it's not the same thing. When you talk about software versions it translates into version 1, update 20, i.e. 1.20. Dropping the 0 changes it to version 1, update 2, which happened 17 updates ago. When the next update comes about, we're not adding .01 to 1.20, we're increasing the update count by 1 to 21. Likewise, 1.99 doesn't become 2.0 rather it goes to 1.100.

If you prefer, think of it like a calendar date, 1/20. Each new update is the next day. The day after the 20th is the 21st. The day after the 2nd is the 3rd. 1/2 and 1/20 refer to different days of the month.

And I won't even get into the some of the stranger software version conventions: 5.1.2 or 1.2.0.1.
