6283185307

6283185307 is the decimal integer 6,283,185,307. In mathematical context, it can be read as the concatenation of the integer part and the first nine digits of the fractional part of 2π, since 2π is approximately 6.283185307179586... Therefore, 6283185307 equals floor(2π × 10^9).

As a result, the number functions as a fixed-point intent in demonstrations or programming examples where 2π is represented with nine-digit precision. It is not equal to 2π itself; rather, it provides a compact integer approximation suitable for certain computational tasks that avoid floating-point arithmetic or require integer constants.

In practical terms, 6283185307 is sometimes used to illustrate precision limits, fixed-point representations, or scaling of irrational constants in educational materials and code samples. It serves as a concrete example of how irrational numbers can be approximated with integers under scaling, rather than as a standalone mathematical constant with independent significance.

Limitations and notes: using 6283185307 as an approximation introduces rounding error relative to the true value of 2π, and the appropriate scale depends on the application's numeric type and precision requirements. The concept is primarily pedagogical and does not have a special global designation beyond its relationship to 2π.
