在 Julia 中获取 x 的最接近整数值 – trunc() 方法

trunc()是 julia 中的内置函数，用于返回与绝对值小于或等于x的指定值x相同类型的最接近的整数值。

Syntax: trunc(x)

Parameters:

• x: Specified value.

Returns: It returns the nearest integral value of the same type as the specified value x whose absolute value is less than or equal to x.

示例 1：

# Julia program to illustrate 
# the use of trunc() method
  
# Getting the nearest integral value 
# of the same type as the specified value 
# x whose absolute value is less
# than or equal to x
println(trunc(3))
println(trunc(0.5))
println(trunc(3.9))

输出：

3
0.0
3.0

示例 2：

# Julia program to illustrate 
# the use of trunc() method
  
# Getting the nearest integral value 
# of the same type as the specified value 
# x whose absolute value is less
# than or equal to x
println(trunc(0))
println(trunc(2))
println(trunc(2.1))
println(trunc(2.5))
println(trunc(2.9))

输出：

0
2
2.0
2.0
2.0
