i assign floating point number variable in r. e.g. k <- 1200.0000002161584854 i got > k [1] 1200 > k+0.00000001 [1] 1200 how keep precision of k ? i have read posts here, but, not find solution. in addition above answers, notice value of k different assigned it. have 15 or 16 digits of precision (most of time more need). k <- 1200.0000002161584854 sprintf('%1.29f',k) "1200.00000021615846890199463814497" note there libraries can increase precision, such gmp , designed around integers.

in postgresql, how generate random unique integer number column, return not exits in table column? see pseudo_encrypt function, implements permutation based on feistel network technique. combined postgres sequence, guarantees unicity of result, randomness human eye. exemple: create sequence seq maxvalue 2147483647; create table tablename( id bigint default pseudo_encrypt(nextval('seq')::int), [other columns] ); the effective range of id here 0...2^32-1 . can adjusted if necessary modifying function. variant 64 bits output space can found at: pseudo_encrypt() function in plpgsql takes bigint . edit: pseudo_encrypt implements 1 permutation, , not accept user-supplied key. if prefer having own permutations, depending on secret keys, may consider skip32 (a 32-bit block cipher based on skipjack, 10 bytes wide keys). a plpgsql function (ported perl/c) available at: https://wiki.postgresql.org/wiki/skip32

i came across strange situation , hope maybe guys can provide clarity. i run sql query in access , results. if enter results window , manually alter record, re-run query, result of query show alteration instead of correct value. how can be? moreover, field alter attribute table, re-running should retrieve value original table, instead on alteration query, right? thanks! when you're using access, long query isn't complicated union , lots of other fun stuff, the queries returned not 'static' 'dynamic': changes make cells directly edit db. yes, query retrieving value table save changes make table. if run query programatically can specify whether make read-only or not results window directly edits tables queries.

i wonder if explain why scanner keeps waiting on input? have stop process on eclipse before code block executes , unsure why scanner keep taking input day . expect press enter , code execute after entering x amount of numbers. public static void main(string[] args){ scanner ascanner = new scanner(system.in); int sum = 0; system.out.println("enter ints : "); while(ascanner.hasnextint()){ sum += ascanner.nextint(); } system.out.println(sum); } if want program take x amount of numbers, have counter , break while loop after has executed x number of times. alternatively, use loop make things easier. you use ctrl+z in eclipse stop console waiting inputs.
