integer part

The integer part of a real number is the part of the number that appears before the decimal . For example, the integer part of π is 3, and the integer part of -2 is -1.

To be more precise, for x, the integer part of x, denoted as [x], is given by

[x]={x if x0x if x<0,

where x and x denote the floor and ceiling of x, respectively.
