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:
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:
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 ))
