multiplyFloats

num1	String Number (floating point number represented as a String) to multiply.
num2	String Number (floating point number represented as a String) to multiply.
precision	String Optional. Number of decimal places to which the product will be rounded. The default value is null.

value	String Product of the numeric values of num1 and num2. If a product cannot be produced, value contains one of the following:
	Value	Description
	Infinity	The computation produces a positive value that overflows the representable range of a float type.
	-Infinity	The computation produces a negative value that overflows the representable range of a float type.
	0.0	The computation produces a value that underflows the representable range of a float type (for example, multiplying a number by infinity).
	NaN	The computation produces a value that cannot be represented as a number (for example, the result of an illegal operation such as multiplying zero by zero or any operation that uses NaN as input, such as 10.0 + NaN = NaN).

Make sure the strings that are passed to the service in num1andnum2 are in a locale-neutral format (that is, using the pattern -####.##). Passing locally formatted strings may result in unexpected results. For example, calling addFloats in a German locale with the arguments 1,23 and 2,34 will result in the value 357, not 3.57 or 3,57.
