### Floor and ceiling functions Wikipedia

en.wikipedia.org/wiki/Floor and ceiling functionsOverviewNotationDefinition and propertiesAppli ionsComputer implementationsSee alsoNotesExternal linksIn mathematics and computer science, the floor function is the function that takes as input a real number displaystyle x , and gives as output the greatest integer less than or equal to displaystyle x , denoted displaystyle operatorname floor x , or displaystyle lfloor xrfloor . Similarly, the ceiling function maps displaystyle x to the least integer greater than or equal to displaystyle x , denoted displaystyle operatorname ceil x , or displaystyle lceil xrceil . For example, displaystyle operatorname floor 2.4 lfloor 2.4rfloor 2 In mathematics and computer science, the floor function is the function that takes as input a real number displaystyle x , and gives as output the greatest integer less than or equal to displaystyle x , denoted displaystyle operatorname floor x , or displaystyle lfloor xrfloor . Similarly, the ceiling function maps displaystyle x to the least integer greater than or equal to displaystyle x , denoted displaystyle operatorname ceil x , or displaystyle lceil xrceil . For example, displaystyle operatorname floor 2.4 lfloor 2.4rfloor 2 and displaystyle operatorname ceil 2.4 lceil 2.4rceil 3 , while displaystyle lfloor 2rfloor lceil 2rceil 2 . The integral part or integer part of x, often denoted displaystyle x , is displaystyle lfloor xrfloor if x is nonnegative, and displaystyle lceil xrceil otherwise. In words, this is the integer that has the largest absolute value less than or equal to the absolute value of x. Wikipedia 183 CCBYSA
