Divides two variables of the same type (Fract, Fixed, or LongInt) or to divide a LongInt or Fixed number by a Fract number.
Fract FracDiv ( Fract x, Fract y );
The first operand, which can be a variable of type Fract or a variable of type Fixed or LongInt.
The second operand, which can be a variable of type Fract or a variable of the same type as the variable in parameter a.
The quotient of the numbers in a and b. If the b parameter is in the format of a Fract number, then the a parameter can be in the format of a Fract, a Fixed, or a LongInt number. If the b parameter is in the format of a Fixed or a LongInt number, then the a parameter must be in the same format.
The returned value is in the format of a Fract number if a and b are both Fract numbers, both Fixed numbers, or both LongInt numbers. Otherwise, the returned value is in the same format as the number in the a parameter.
Division by zero results in $8000000 if a is negative, and $7FFFFFFF otherwise; thus the special case 0/0 yields $7FFFFFFF.
Supported in Carbon. Available in Carbon 1.0.2 and later when running Mac OS 8.1 or later.
