fix

Round toward zero

Description

example

Y = fix(X) rounds each element of X to the nearest integer toward zero. This operation effectively truncates the numbers in X to integers by removing the decimal portion of each number:

  • For positive numbers, the behavior of fix is the same as floor.

  • For negative numbers, the behavior of fix is the same as ceil.

Examples

collapse all

X = [-1.9 -3.4; 1.6 2.5; -4.5 4.5]
X = 3×2

   -1.9000   -3.4000
    1.6000    2.5000
   -4.5000    4.5000

Y = fix(X)
Y = 3×2

    -1    -3
     1     2
    -4     4

X = [1.4+2.3i 3.1-2.2i -5.3+10.9i]
X = 1×3 complex

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

Y = fix(X)
Y = 1×3 complex

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

Input Arguments

collapse all

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.
