COMECricket overs are not decimal numbers
The digits after the dot in cricket over notation count valid balls in the current over. They are not a decimal fraction of an over.
Convert a simple example
In an illustrative score, 12.4 overs means twelve complete overs plus four valid balls. With six valid balls in each completed over, that is 76 valid balls. It is not 12.4 multiplied by six.
Watch the next transition
After the next valid ball, the display would show 12.5; after another, 13.0. Wides and no-balls normally do not count among the six valid balls, so the number of deliveries attempted can differ from the valid-ball count.
Use the notation carefully
For a rate calculation, convert balls correctly first. When a scorecard uses a different display layout, check its labels. The example explains the notation and is not a current IPL score.
A useful next step
Read the MCC over rule and the IPL overview for context before interpreting a match's remaining balls.
