Rounding of numbers

Description

Round a number to the nearest value.

Usage

integer_round(x, upper5 = TRUE)
decimal_floor(x, digits = 1)
decimal_ceiling(x, digits = 1)
integer_floor(x, base=10)
integer_ceiling(x, base=10)

Arguments

x	A numeric vector.
upper5	Logical value that regulates the rounding in presence of the decimal .5.
digits	Integer indicating the number of decimal places to consider.
base	Integer value to use as step in rounding. The x values will be rounded to the nearest lower/upper base value.

Details

integer_round rounds a decimal number to the nearest integer. When the decimal is exactly .5, the number is rounded to the upper integer (upper5 = T). The opposite behavior is obtained when upper5 = F.

decimal_floor and decimal_ceiling round a decimal number to the nearest decimal digit, specified by digits.

integer_floor and integer_ceiling round a number to the nearest integer value specified by base.

decimal_floor(x)
decimal_ceiling(x)
x <- c(1, 9, 24, 32, 59)
