NAME
       compound(), compoundf(), compoundl(), compoundw(), compoundq() - compound interest factor

SYNOPSIS
DESCRIPTION
       The function computes the compound interest factor:

	      (1 + rate) ** periods

       is a version of it takes arguments and returns a result.

       is a version of it takes arguments and returns a result.

       is an version of it takes arguments and returns an result.

       is equivalent to on HP-UX systems.

USAGE
       To use these functions, compile either with the default option or with the and options.

       To use or compile also with the option.	Make sure your program includes

       Link in the math library by specifying on the compiler or linker command line.

RETURN VALUE
       If periods equals zero, returns 1.0.

       Else, if either argument is a NaN, returns a NaN.

       Else, if rate is less than -1, returns a NaN and raises the invalid exception.

       Else, if rate equals -1, is equivalent to

       Else, if rate equals +INFINITY, is equivalent to

       Else, if periods is infinite and rate equals zero, returns 1.0.

       Else, if periods is infinite and rate does not equal zero, is equivalent to

       returns a properly signed infinity in lieu of a value whose magnitude is too large, and raises the overflow and inexact exceptions.

       raises  the  underflow and inexact exceptions whenever a result is tiny (essentially  denormal  or  zero) and thereby suffers loss of accu-
       racy, and may raise those exceptions if the result is merely tiny.

ERRORS
       No errors are defined.
