NAME
|
|
dm2d, dms2d - convert degrees, minutes, and seconds to degrees
|
|
|
|
SYNOPSIS
|
|
dm2d(d, m [,rnd])
|
|
dms2d(d, m, s [,rnd])
|
|
|
|
TYPES
|
|
d real
|
|
m real
|
|
s real (defaults to 0)
|
|
rnd nonnegative integer, defaults to config("mod")
|
|
|
|
return degrees
|
|
|
|
DESCRIPTION
|
|
Convert degrees, m minutes, and s seconds returning degrees.
|
|
|
|
The return value in degrees, is equivalent to the following:
|
|
|
|
mod(d + m/60 + s/3600, 360, rnd);
|
|
|
|
Depending on the rounding mode, the return could be a real value
|
|
in the interval [0, 360) or a real value in the interval (-360, 0].
|
|
For the default round mode, the return value is in the interval [0, 360).
|
|
|
|
A missing rnd defaults to config("mod").
|
|
For more information on the effects of rnd, see "help mod".
|
|
|
|
The dm2d(d, m, rnd) builtin is an alias for dms2d(d, m, 0, rnd).
