# al\_itofix(3)

Allegro 5 API

## NAME

al\_itofix - Allegro 5 API

## SYNOPSIS

-

  ```
  #include <allegro5/allegro.h>
  al_fixed al_itofix(int x);
  ```

## DESCRIPTION

Converts an integer to fixed point. This is the same thing as x\<\<16. Remember that overflows (trying to convert an integer greater than 32767) and underflows (trying to convert an integer lesser than -32768) are not detected even in debug builds! The values simply “wrap around”.

Example:

-

  ```
  al_fixed number;
  /* This conversion is OK. */
  number = al_itofix(100);
  assert(al_fixtoi(number) == 100);
  number = al_itofix(64000);
  /* This check will fail in debug builds. */
  assert(al_fixtoi(number) == 64000);
  ```

## RETURN VALUE

Returns the value of the integer converted to fixed point ignoring overflows.
