No. An irratioinal number is a number that cannot be expressed as a fraction
6.23 = 623/1000 (you can check this on your calculator, if you'd like).
The existence of this fraction means, by the definition given above, the 6.23 is not an irrational number.
In more applied terms, any number with a decimal without repeating terms is ALWAYS rational. In decimals with repeating terms, as long as the terms follow some pattern, the number is rational.
example:
0.3333333333... is rational because the numbers follow a pattern (and because this = 1/3).
pi (or 3.141592.....) is not rational because the numbers do not follow a pattern.
