IPL Overs Explained: What 8.3 Means
In a cricket score, 8.3 overs means eight completed overs and three valid balls of the next over. The digit after the point is a ball count, so it should not be read as a decimal fraction.
Count in groups of six
The MCC law describes an over as six valid balls. To convert 8.3 displayed overs, calculate eight times six plus three: 51 valid balls. The next valid ball makes the display 8.4, and after six valid balls the completed-over count advances.

Read runs separately from balls
Runs can be added through boundaries, running and extras. Wides and no-balls do not count as valid balls in the over, so the score can change while the displayed ball count stays the same. Follow the official scorer’s display.
Use the innings context
A valid-ball count tells you how much of an innings has been played, not whether the match has finished. Read the innings number, batting team, target and match status alongside it. Any reduced allocation changes how many balls remain.
