compound(3M) compound(3M) 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. SEE ALSO

annuity(3M) annuity(3M) NAME
annuity(), annuityf(), annuityl(), annuityw(), annuityq() - present value factor for annuity SYNOPSIS
DESCRIPTION
The function computes the present value factor for an annuity: (1 - (1 + rate) ** (-periods)) / rate 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 compile 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 0.0. Else, if rate equals zero, returns periods. Else, if either argument is a NaN, returns a NaN. Else, if rate < -1, returns a NaN and raises the invalid exception. Else, if rate = -1 and periods = +INFINITY, returns +INFINITY. Else, if rate equals -1 and periods > 0, is equivalent to Else, if rate equals -1, returns -1. Else, if rate equals +INFINITY and periods >= 0, returns +0.0. Else, if rate equals +INFINITY and -1 < periods < 0, returns -0.0. Else, if rate equals +INFINITY and periods = -1, returns -1. Else, if rate equals +INFINITY, returns -INFINITY. Else, if periods is infinite and (rate * periods) > 0, is equivalent to Else, if periods is infinite, returns periods. 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 accuracy, and may raise those exceptions if the result is merely tiny.
