Calculate the Floor and Ceiling values in R Programming – floor() and ceiling() Function

** floor()** function in R Language returns the largest integer that is smaller than or equal to value passed to it as argument(i.e : rounds downs to the nearest integer).

Syntax:floor(x)

Parameter:x:Value to be rounded off

**Example 1:**

`# R program to calculate floor value ` ` ` `# Using floor() method ` `answer1 <` `-` `floor(` `1.2` `) ` `answer2 <` `-` `floor(` `1.5` `) ` `answer3 <` `-` `floor(` `2.6` `) ` `answer4 <` `-` `floor(` `-` `2.6` `) ` ` ` `print` `(answer1) ` `print` `(answer2) ` `print` `(answer3) ` `print` `(answer4) ` |

**Output:**

1 1 2 -3

#### ceiling() Function

** ceiling()** function in R Language returns the smallest integer that is greater than or equal to the value passed to it as argument(i.e : rounds up to the nearest integer).

Syntax:ceiling(x)

Parameter:x:Value to be rounded off

**Example 1:**

`# R program to calculate ceiling value ` ` ` `# Using ceiling() method ` `answer1 <` `-` `ceiling(` `1.2` `) ` `answer2 <` `-` `ceiling(` `1.5` `) ` `answer3 <` `-` `ceiling(` `2.6` `) ` `answer4 <` `-` `ceiling(` `-` `2.6` `) ` ` ` `print` `(answer1) ` `print` `(answer2) ` `print` `(answer3) ` `print` `(answer4) ` |

**Output:**
