Round/eo: what changed
Revision 1 to 2. Removed lines have a minus sign; added lines have a plus sign.
| Old | New | Line | |
|---|---|---|---|
| 1 | 1 | La [[RTL]] [[System unit|Systema unuo]] enhavas [[Function|funkcion]] **Round**, kiu rondigas [[Real]]-tipan valoron al [[Integer|Entjera]]-tipa valoro. Ĝia eniga parametro estas [[expression|esprimo]] kaj Round revenigos [[Int64]] valoron kiu estas la valoro de la enigo rondigita al la plej proksima entjero. Se la enigo estas ekzakte meze de la du entjeroj - N.5 - tiam "rondigo de bakisto" estas uzata, kies rezulto estas la plej proksima para nombro. | |

| 14 | 14 | WriteLn( Round(8.3) ); | |
| 15 | 15 | // examples of "bankers rounding" - .5 is adjusted to the nearest even number | |
| 16 | 16 | WriteLn( Round(2.5) ); | |
| 17 | 17 | WriteLn( Round(3.5) ); | |
