SYNOPSIS

10       #include <allegro.h>
11
12
13       extern const fixed fixtorad_r;

DESCRIPTION

16       This constant gives a ratio which can be used to convert a fixed  point
17       number in binary angle format to a fixed point number in radians. Exam‐
18       ple:
19
20          fixed rad_angle, binary_angle;
21          /* Set the binary angle to 90 degrees. */
22          binary_angle = 64;
23          /* Now convert to radians (about 1.57). */
24          rad_angle = fixmul(binary_angle, fixtorad_r);
