Availability:Arithmetic function (see is/2)
resource error is raised if the result cannot be
represented. See section
2.19.2 for the maximum size of an integer. Note that this limit is
significantly smaller if the system is built using GMP and the C type long
is smaller than 64 bits, as is the case on Windows.
The ISO standard demands a float result for all inputs and introduces ^/2 for integer exponentiation. The function float/1 can be used on one or both arguments to force a floating point result. Note that casting the input result in a floating point computation, while casting the output performs integer exponentiation followed by a conversion to float.
