A number literal is composed using the digits 0 to 9 and a decimal point (if desired). The number literal is automatically assigned the data type VASTINT, with a number of decimal places equal to the number of places shown in the expression.

The following numbers are examples of valid number literals:

5 234 0.5 468.55

The following groups of digits are not number literals

56,789 1 23

because the software does not enable commas or spaces to be used inside numbers.
