to_number( value )
ToNumber( value )
Description
The ToNumber
function converts a value to a numeric literal, if
possible.
Attempting to convert a value to a number which has no numeric representation results in an "invalid argument" error.
Parameters
Argument | Type | Definition and Requirements |
---|---|---|
|
Any |
The value to attempt to convert to a number type. |
Examples
The query below executes an array of independent ToNumber
operations
and returns the results in an array. The result array position matches
the execution array position. The first operation converts a floating
point literal to a number. The second operation takes an integer
literal and converts it to a number. The last operation converts a
string to a number.
Value result = await client.Query(
Arr(
ToNumber(1234.5678),
ToNumber(1234),
ToNumber("123")
)
);
Arr(DoubleV(1234.5678), LongV(1234), LongV(123))
result, _ := client.Query(f.Arr{
f.ToNumber(1234.5678),
f.ToNumber(1234),
f.ToNumber("123")})
fmt.Println(result)
[1234.5678 1234 123]
System.out.println(
client.query(Arr(
ToNumber(Value(1234.5678)),
ToNumber(Value(1234)),
ToNumber(Value("123"))
)).get());
[1234.5678, 1234, 123]
client.query([
q.ToNumber(1234.5678),
q.ToNumber(1234),
q.ToNumber('123'),
]).then((ret) => console.log(ret))
[ 1234.5678, 1234, 123 ]
print(client.query([
q.to_number(1234.5678),
q.to_number(1234),
q.to_number("123")
]))
[1234.5678, 1234, 123]

client.query(
Arr(
ToNumber(1234.5678),
ToNumber(1234),

)

5.seconds
))
