Round a numeric vector; halves will be rounded up, ala Microsoft Excel.


In base R round(), halves are rounded to even, e.g., 12.5 and 11.5 are both rounded to 12. This function rounds 12.5 to 13 (assuming digits = 0). Negative halves are rounded away from zero, e.g., -0.5 is rounded to -1.

This may skew subsequent statistical analysis of the data, but may be desirable in certain contexts. This function is implemented exactly from; see that question and comments for discussion of this issue.


round_half_up(x, digits = 0)



a numeric vector to round.


how many digits should be displayed after the decimal point?


round_half_up(1.125, 2)
round_half_up(1.125, 1)
round_half_up(-0.5, 0) # negatives get rounded away from zero
