Double Double values should written in scientific notation or be followed by d or D to be interpreted as double. Otherwise they are interpreted as decimals.
1.5d
5D
-.1415d
-4.73E-2
java.lang.Double
Float Float values can be written in scientific notation. They should be followed by f or F to be interpreted as float. Otherwise they are interpreted as double if they contain scientific notation, or decimal if they do not.
3.1415f
1.5e-2f
5F
java.lang.Float
Decimal Decimals are numbers with a decimal point
0.3

Bytes Bytes should be written with hexadecimal characters in lowercase or uppercase, prefixed by 0x or 0X.
0xFFFFFF
0X1234567890
0x0a6e
byte[]
Date Dates should be delimited by single or double quotes. They are composed of a year, month and day in the format yyyyMMdd, yyyy/MM/dd or yyyy-MM-dd. To evaluate them as dates instead of strings, you need to use a toDate function. See Data type functions.
'2019-08-05'
"1981/09/12"
'20170223'
java.time.LocalDate
Time Times should be delimited by single or double quotes. They are composed of hours and minutes, and can also contain seconds, milliseconds, and a timezone. The format should be HH:mm, hh:mm:ss or HH:mm:ss.SSS To evaluate them as times instead of strings, you need to use a toTime function.
"09:44"
'12:32:25'
"09:51:32.568"
"01:02:03.456+03:00"
  • java.time.LocalTime
  • java class java.time.OffsetTime
Datetime Datetimes should be delimited by single or double quotes. They are composed of a date and a time, with an optional timezone. The format should follow the international standard ISO 8601. To evaluate them as datetimes instead of strings, you need to use a toDateTime function.
"2017-07-02T15:04:05.567-08:00"
'2024-05-07T14:27'
  • java.time.OffsetDateTime
  • java class java.time.LocalDateTime
