0 the numbers used to write a number to be as exact as is needed:
2.3945 to two significant digits is 2.4.
Within-run error expressed as 2m in the last significant digits.
For ease of presentation, discounted costs and survival are shown rounded to four significant digits.
Yet, this limit is twice the number of significant digits attainable by the general-purpose ode113.
The asymptotic formulae (7.5), (7.12) give for such steep waves not less than ten significant digits for the phase velocity and wave steepness.
In real-world measuring situations, improving the measurement technique will eventually begin yielding unpredictable least significant digits.
The typical precision of a slide rule is about three significant digits, compared to many digits on digital calculators.
Questions must be answered to the proper number of significant digits, with small variation in the final significant digit acceptable.
Numerical approximations sometimes result from using a small number of significant digits.
