### FixedDivide

You can use the `FixedDivide` function to return the quotient of a dividend and divisor.

```Fixed FixedDivide (Fixed dividend, Fixed divisor);
```
`dividend`
The number to be divided.
`divisor`
The number by which the dividend is to be divided.
function result
The quotient of the dividend and the divisor.
##### DESCRIPTION
The `FixedDivide` function divides the `dividend` parameter by the `divisor` parameter and returns the quotient. The format of the fixed number returned depends on the respective number formats of the `dividend` and `divisor` parameters. The operation has a bias of 16 bits; in general, the bias of the resulting number is the difference between the biases of the input numbers, shifted left by 16 bits. If the `divisor` parameter is fixed, then the result will be the same fixed-point format as the dividend. If both the dividend and divisor are the same fixed-point format, the result will be in `Fixed` format.

Table 8-4 shows the bias for the quotient of two numbers that are of dissimilar formats. The dashed line indicates that the resulting bias is not equivalent to long, fixed, or fract. Use the rules of the operation to determine it.

##### SPECIAL CONSIDERATIONS
In the case of overflow, `FixedDivide` pins its result to either the `gxPositiveInfinity` or `gxNegativeInfinity` constant.
