`fix`

Rounds toward zero, discarding the fractional part.

Category: Language Fundamentals > Operators and Elementary Operations

Syntax

Y = fix(X)

Rounds each element of X: toward zero.

Description

fix truncates: positive numbers behave like floor and negative numbers like ceil, so fix(2.7) is 2 and fix(-2.7) is -2.

It matches the result of integer division in languages that truncate, and rem(a,b) equals a - b*fix(a/b).

Input arguments

X: Numeric array. For complex values the real and imaginary parts are processed separately. Integer types are returned unchanged.

Output arguments

Y: Array of the same size and class as X, holding integer values.

Example

fix([2.7 -2.7 0.5 -0.5])
fix(-7/2)

Output

ans = 1×4

     2    -2     0     0
ans = -3
