fix

Round toward zero

Syntax

Description

example

Y = fix(X) rounds each element of X to the nearest integer toward zero. For positive X, the behavior of fix is the same as floor. For negative X, the behavior of fix is the same as ceil.

Round Matrix Elements Toward Zero

X = [-1.9 -3.4; 1.6 2.5; -4.5 4.5]
X =

   -1.9000   -3.4000
    1.6000    2.5000
   -4.5000    4.5000

Y = fix(X)
Y =

    -1    -3
     1     2
    -4     4

Round Complex Numbers Toward Zero

X = [1.4+2.3i 3.1-2.2i -5.3+10.9i]
X =

   1.4000 + 2.3000i   3.1000 - 2.2000i  -5.3000 +10.9000i

Y = fix(X)
Y =

   1.0000 + 2.0000i   3.0000 - 2.0000i  -5.0000 +10.0000i

Input Arguments

X — Input arrayscalar | vector | matrix | multidimensional array

Input array, specified as a scalar, vector, matrix, or multidimensional array. For complex X, fix treats the real and imaginary parts independently.

fix converts logical and char elements of X into double values.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | char | logical
Complex Number Support: Yes
