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. ERRORS
No errors are defined. SEE ALSO

scalb(3M) scalb(3M) NAME
scalb(), scalbf(), scalbl(), scalbw(), scalbq() - scale exponent of a radix-independent floating-point number SYNOPSIS
HP Integrity Server Only DESCRIPTION
The function returns where r is the radix of the machine's floating-point arithmetic. The radix r is 2 on all PA-RISC and Integrity servers. Integrity Server Only 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 (for Integrity servers) 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
and are equivalent. If y returns x. If x is +0 and y is +INFINITY, returns a NaN and raises the invalid exception. If x is +0 and y is an integer less than +INFINITY, returns +0. If x is +INFINITY and y is an integer greater than -INFINITY, returns +INFINITY. If x is finite and positive-signed and y is -INFINITY, returns +0. If x is positive and y is +INFINITY, returns +INFINITY. If x is +INFINITY and y is -INFINITY, returns a NaN. If x or y is NaN, returns a NaN. 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. ERRORS
If the correct value would overflow or underflow, sets to [ERANGE]. Integrity Server Only HP-UX functions on Integrity servers do not set by default. For setting, compile with the option. SEE ALSO
