round

Round to nearest integer

📝Syntax

C = round(A)
C = round(A, N)
C = round(A, N, 'decimals')
C = round(A, N, 'significant')

📥Input Arguments

Parameter	Description
A	a variable
N	number of digits: real integer scalar.
type	'decimals' (default) or 'significant'.

📤Output Arguments

Parameter	Description
C	result of round.

📄Description

round rounds the elements to the nearest integers.

round(A, N) rounds to N digits to the right of the decimal point (N may be negative). This is the same as round(A, N, 'decimals').

round(A, N, 'significant') rounds to N significant digits; here N must be positive.

Sparse single and sparse single complex inputs are supported. Only stored nonzero entries are rounded and the result keeps the sparse storage and the input precision.

💡Examples

round(pi)

Round to a number of decimal or significant digits.

round(3.14159, 2)
round(12345, 2, 'significant')

Round a sparse single matrix to nearest integers.

S = sparse(single([1.2 0; -2.7 3.1]));
C = round(S)
