# Getting rounded value of a number in Julia – round() Method

The `round()` is an inbuilt function in julia which is used to round the specified number in different ways which are illustrated below-

• The default round process is done to the nearest integer, with ties (fractional values of 0.5) being rounded to the nearest even integer.
• The specified value x is rounded to an integer value and returns a value of the given type T or of the same type of x.
• If the digits keyword parameter is given, it rounds to the specified number of digits after the decimal place (or before if negative), in the given base.
• If the sigdigits keyword parameter is given, it rounds to the specified number of significant digits, in the given base.

Syntax:
round(x)
round(T, x)
round(x, digits::Integer, base)
round(x, sigdigits::Integer, base)

Parameters:

• x: Specified number
• T: Specified number type
• digits: Specified digit values
• base: Specified base in which results are coming
• sigdigits: Specified significant digits

Returns: It returns the rounded value of the specified number.

Example 1:

 `# Julia program to illustrate  ` `# the use of round() method ` ` `  `# Getting the rounded values ` `println(``round``(``2``)) ` `println(``round``(``2.3``)) ` `println(``round``(``2.9``)) ` `println(``round``(``0.5``)) ` `println(``round``(``2.5``)) ` `println(``round``(``3.5``)) `

Output:

```2
2.0
3.0
0.0
2.0
4.0
```

Example 2:

 `# Julia program to illustrate  ` `# the use of round() method ` ` `  `# Getting the rounded values ` `println(``round``(pi; digits ``=` `3``)) ` `println(``round``(``56.7685``; digits ``=` `3``)) ` `println(``round``(pi; digits ``=` `3``, base ``=` `2``)) ` `println(``round``(``55.98634``; digits ``=` `3``, base ``=` `2``)) ` `println(``round``(``324.675``; sigdigits ``=` `2``)) ` `println(``round``(``232.97634``; sigdigits ``=` `4``, base ``=` `2``)) `
