Integer Literals
Integer literals are specified by a sequence of up to 10 digits and an optional sign, in the following format:
[+|-] digit {digit} [e digit]
Integer literals are represented internally as either an i4 or a i2, depending on the value of the literal. If the literal is within the range -32,768 to +32,767, it is represented as a i2. If its value is within the range -2,147,483,648 to +2,147,483,647 but outside the range of a i2, it is represented as an i4.
You can specify integers using a simplified scientific notation, similar to the way floating point values are specified. To specify an exponent, follow the integer value with the letter "e" and the value of the exponent. This notation is useful for specifying large values; for example, to specify 100,000 you can use exponential notation as follows:
10e5
