long

Syntax long (value)
Params value is the object whose datatype you wish to coerce to be a 32-bit signed value.
Action Coerces the datatype of value to be a 32-bit signed numeric value if possible.
Returns The numeric value produced by the coercion if it is successful; otherwise an error.
Examples long ("123456")

   » 123456

long (1575.23)

   » 1575

long (infinity)

   » 2147483647

The example above shows the largest value that can be represented by a 32-bit signed number.

long (".009")

   » 0

long (123.98)

   » 123

The example above shows that long truncates the value rather than rounding it.

Errors If value is an improperly formatted string, or a type that cannot be coerced to a number, an error message is generated.
Notes See the discussion of datatypes in Chapter 1 of the UserTalk Reference Guide for information on the range of values that can be represented by a long number, and for other details.
