**Log significant figures** are well-known figures in Mathematic terms and if you love mathematics you’d surely love hearing this word time and again. The least and log significant figures are often known as significant digits which carry something which contributes to its measurement resolution. The log and the least significant figures include all the figures except the following ones

- All numbers which leads to zero (Zero Leading Numbers)
- All numbers which have trailing zeros included. For instance, when trailing numbers are merely used as a placeholder to indicate the scaling of the number.
- All the numbers which have spurious digits included. For example, all the calculations which lead you to the greater precision of original data, measurement or reports which are generated by any machines with the help of equipment support. These types of calculations include spurious digits.

Let’s drive our attention now to Log Significant Figures (Significant Arithmetic) which are approximate rules for roughly calculations and significance throughout a computation. The other well-known rule which is well modified than this one is “Propagation of Uncertainty”

Identifying all these figure isn’t a difficult task but you must have a bit of knowledge before going for any identification. Follow few steps to identify significant figures

- All numbers are significant except the zero. For example 123456789
- All the zeros which comes in-between any non-zero digits are significant. For example 105, 107, 209, 203
- All the leading zeros for any numbers aren’t significant. For example 0.21, 0.214

Note: These steps are known as Concise Rules

Significant Notation rules are same for almost all the figures in mathematics but there are slightly different rules for Log and Least significant figures. And we all know that a small mistake in following rules can change the course of that question and definitely the answer as well.

In most of the cases, the normalized form of the scientific notation, placeholders and trailing digits are occurred to be the part of significant figures. And the potential ambiguity for the scientific notation of tailing numbers must always be zero which gets eliminated because of non-significant number.

And the parts of all the representation which includes the significant figures (Base or Exponent) are known as mantissa.

Accuracy and Precision sometimes in Log and Least Significant Figures might be a difficult task to do because in different technical fields, “Accuracy” refers to the true value in closeness of the given result or measurement, Whereas “Precision” refers to stability of repeated numbers of that measurement.

But according to the rules of Significant figures, Accuracy and Precision roughly connects to the newer concept of trueness.

In computations, a Log and Significant figure typically uses a form of binary number which round offs latterly to significant figures. The correctness of all the computations can be referred to relative errors because any sort of error can happen in big computations.
