IBMBMBL*

IBMBMBL is a routine that performs exponentiation of the constant e with a long floating point real number. This routine is invoked by the EXP(x) command, and yields a value that is approximately e to the power of x. This routine might also be called for trigometric functions, calculations with long floating point or complex numbers, and relative error calculations.
