Numeric Data Type

Select from the available options the type of the random numbers you will generate.

NOTE: Numeric Data Type applies to all the output options listed on the form:

Range of Numbers, Numeric Offset From Current Number and Number Sequence.

Range of Numbers

Select this option if you want to generate numbers within a minimum and maximum range.

Integer

Signed integers can have negative or positive values.

Unsigned integers can only have positive values.

Range of Values

Type	Signed	Unsigned
64-bit	–9,223,372,036,854,775,808 to 9,223,372,036,854,775,807	0 to 18,446,744,073,709,551,615
32-bit	-2,147,483,648 to 2,147,483,647	0 to 4,294,967,295
16-bit	-32,768 to 32,767	0 to 65,535
8-bit	-128 to 127	0 to 255

Double, Float, Decimal

Range of Values

Type	Range	Precision
Double	±5.0 × 10−324 to ±1.7 × 10308	15-16 digits
Float	-3.4 × 1038to +3.4 × 1038	7 digits
Decimal	(-7.9 x 1028 to 7.9 x 1028) / (100 to 28)	28-29 significant digits

Numeric Offset From Current Number

Select this option to generate a random smaller or large number that is offset from the current value of the data field in the data source.

Number Sequence

Select this option to generate a set of sequential numbers starting at a given number up to a maximum value. You will also specify how much to increment the numbers in the sequence as the numbers are generated.

Examples:

Example 1:

Numeric Data Type = Integer, 32-bit

Range of Numbers = 1 to 1000
