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).

; print dm2d(203, 325.5594);
