Description

This unit contains constants and functions used in determining the mathematical accuracy of the language. All routines in the Limits module are exported qualified (and thus must be prefaced with "Limits.") except maxint, maxnat, minint and minnat, which are exported unqualified (this means you can call those entry points directly).

Entry Points

DefaultFW   Default fraction width used in printing using the "put" statement. DefaultEW   Default exponent width used in printing using the "put" statement. minint   The minimum integer in Turing (exported unqualified). maxint   The maximum integer in Turing (exported unqualified). minnat   The minimum natural number in Turing (exported unqualified). maxnat   The maximum natural number in Turing (exported unqualified). Real numbers are represented in Turing as: f * (radix ** e) or 0 where for non-zero f: (1 / radix) <= abs (f) and abs (f) < 1.0 minexp <= e and e <= maxexp. Radix   The "radix" (usually 2). NumDigits   The number of radix digits in f. MinExp   "minexp" (the smallest exponent allowed). MaxExp   "maxexp" (the largest exponent allowed). GetExp   Function that returns the value of "e". SetExp   Procedure that sets the value of "e". Rreb   The relative round-off error bound.
