dígito significativo
- When reporting measurements, it's important to include all significant digits to ensure accuracy.
And they would produce numbers for these tables, engineering tables that the more, the more iterations they did, the more significant digits came out.

One piece is the significant digit and the other piece is the power of two.
-
In scientific calculations, only the significant digits are considered when determining precision.
-
And when you subtract them right, then most of the significant digits cancel one another.

As would be expected, the choice of exchange rate and the number of significant digits used in the conversion can have an impact on the value and consistency of currency translation.

Morphology
A B1 learner who knows 'significant' (important) and 'digit' (numerical symbol) can grasp the general idea of a 'digit that matters' in a number, so the phrase has an intuitively compositional core. However, the precise technical rules (first non-zero, trailing zeros indicating precision) are domain-specific and not predictable from the words alone, so full understanding requires prior exposure or instruction.
Etymology
Significant digit comes from the idea of the digits that really 'count' for how exact a number is. The first number that is not zero starts the significant part and any final zeros that show how exact the measurement was are also counted, so the phrase means the digits that tell how exact a number is.
