Numbers with lots of decimals may be a bit cryptic. Thus, for instance, using the calc function may be a good alternative to improve readability and understandability.

Noncompliant Code Example

With a maximum allowed precision of 3: 
.mybox {
  bottom: 3.3333px; /* Noncompliant */
}

Compliant Solution

With a maximum allowed precision of 3: 
.mybox {
  bottom: 3.333px;
}

OR

.mybox {
  bottom: calc(10px / 3);
}
