R语言内置函数(Built-in Functions) R中几乎所有的事情都是通过函数完成的。 常用的数值运算函数 Function Description abs(x) 绝对值、absolute value sqrt(x) 开平方根、square root ceiling(x) 向上取整近似值、ceiling(3.475) is 4 floor(x) 向下取整近似值、floor(3.475) is 3 trunc(x) 小数点去除、trun...
R 语言中的 trunc() 函数用于返回小于或等于 x 的最大整数(即:向下舍入最近的整数)。 trunc() 函数表现为负数的上限函数和正数的下限函数。 用法:trunc(x) 参数: x:要四舍五入的数值 范例1: # R program to calculatetruncvalue# Usingtrunc() methodanswer1 <-trunc(3.4) answer2 <-trunc(-3.4) ans...
Definition of trunc R function: The trunc function truncates (i.e. cuts off) the decimal places of a numeric input.Definition of signif R function: The signif function rounds a numeric input to a specified number of digits.In the following, you can find the R code that computes the ...
Int(x)函数 取整数(实数) 定义:function Int(X: Real): Real; 注意:X是实型数,返回值也是实型的;返回的是X的整数部分,也就是说,X被截尾了(而不是四舍五入)例子: var R: Real; begin R := Int(123.4567); { 123.0 } R := Int(-123.456); { -123.0 } end. 1. 2. 3. 4. 5. 4 Trun...
For example, this is useful when performing a GROUP BY on DateTime data based on coarser time ranges (such as GROUP BY “Quarter” given DateTime values). The syntax of the function is: <TruncExpr> ::= TRUNC(<expr>,<DateTimeUnit>) ...
Ein negativer Wert fürintegergibt die Anzahl der signifikanten Stellen an, die links neben dem Dezimaltrennzeichen steht. Beispiele: In der folgenden Anweisung wird die positive Zahl 2 verwendet. Die ersten beiden Stellen rechts vom Dezimaltrennzeichen bleiben stehen, und die darauf folgenden Ste...
