SYNOPSISDESCRIPTION
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 com‐
mand 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 equiva‐
lent 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 accuracy,
and may raise those exceptions if the result is merely tiny.
ERRORS
No errors are defined.
