Number type

Number is the supertype of all numeric types, including integers and real numbers such as decimals and floats.

Ordinal

An ordinal is a natural number representing a position in a sequence, such as 1st, 2nd, 3rd, and so on.

The underlying type is a 64-bit integer. However, because ordinals are unsigned, the range is limited to 1 through 9223372036854775807.

Integer

An integer represents a whole number, either positive or negative.

The underlying type is a 64-bit signed integer, meaning that values can range from -9223372036854775808 to 9223372036854775807.

Decimal

A decimal refers to precise real numbers that include a fractional part.

Unlike integers, decimals do not have maximum or minimum values but do have a maximum precision of 28 significant digits.

Float

Floats represent approximated real numbers and are commonly used for continuous values that do not require precision.

The underlying float type is a 64-bit floating-point number. It can accurately represent integers within the range of -9007199254740991 to 9007199254740991 and a subset of decimal numbers.
