"SetPrecision." Wolfram Language & System Documentation Center. BUILT-IN SYMBOL See Also Overflow Overflow Overflow represents a number too large to represent explicitly on your computer system. If computations that involve overflow are done with machine reals in C the results are slightly different from the case of machine integers. Wolfram Research (1991), SetPrecision, Wolfram Language function, (updated 2003). In computer programming, an integer overflow occurs when an arithmetic operation attempts to create a numeric value that is outside of the range that can be represented with a given number of digits either higher than the maximum or lower than the minimum representable value. An overflow causes an error while running the function. SetPrecision does not modify expr itself.Ĭite this as: Wolfram Research (1991), SetPrecision, Wolfram Language function, (updated 2003).0.004`25 generates a number with all trailing digits zero and precision 25 on any computer system.SetPrecision will first expose any hidden extra digits in the internal binary representation of a number, and, only after these are exhausted, add trailing zeros.If expr contains machine ‐precision numbers, SetPrecision can give results that differ from one computer system to another.If there are numbers too large or small to represent machine-precision numbers, SetPrecision will convert them to arbitrary-precision numbers with precision $MachinePrecision.SetPrecision converts numbers in expr to machine precision.SetPrecision returns an arbitrary ‐precision number, even if the precision requested is less than $MachinePrecision.In base 10, the additional digits are usually not zeros. When SetPrecision is used to increase the precision of a number, the number is padded with zeros.
