# op:float-mod

Return the remainder of dividing $float-var1 by $float-var2. The mod operator invokes the float-mod operator.

To learn more about using this operator with NaN, positive infinity, or negative infinity operands, see the W3C numeric-mod operator description.

### Signatures

op:float-mod(xs:float $float-var1, xs:float $float-var2) —> xs:float

### Arguments

Data Type | Argument | Description
--- | --- | ---
xs:float | $float-var1 | Represents a 32 bit floating point number, for example: 1.1.
xs:float | $float-var2 | Represents a 32 bit floating point number, for example: 1.1.

### Returns

Returns the remainder of dividing $float-var1 by $float-var2.

### Examples

#### Simple

Invoking float-mod("1.25","1.0") returns the floating point value: .25 because 1.25 divided by 1.0 results in 1 with the remainder: .25. The remainder: .25 is returned as shown in the following example query:

    <float-mod>{op:float-mod("1.25","1.0")}</float-mod>

The preceding query generates the following result:

    <float-mod>0.25</float-mod>

#### Divide by Zero

Invoking float-mod("2.2","0")returns a NaN (Not a Number) value as shown in the following example query:

    <float-mod>{op:float-mod("2.2","0")}</float-mod>

The preceding query generates the following result:

    <float-mod>NaN</float-mod>
