# op:double-multiply

Multiplies $double-var1 by $double-var2. The * operator invokes the double-multiply operator.

### Signatures

op:double-multiply(xs:double $double-var1, xs:double $double-var2) —> xs:double

### Arguments

Data Type | Argument | Description
--- | --- | ---
xs:double | $double-var1 | Represents a double precision (64 bit) floating point number, for example: 1.1.
xs:double | $double-var2 | Represents a double precision (64 bit) floating point number, for example: 1.1.

### Returns

Returns the double precision (64 bit) floating point value of multiplying $double-var1 by $double-var2.

### Examples

#### Simple

Invoking double-multiply("2.0","3.0") returns the double precision floating point value: 6.0 as shown in the following example query:

    <double-multiply>{op:double-multiply("2.0","3.0")}</double-multiply>

The preceding query generates the following result:

    <double-multiply>6.0</double-multiply>
