In Degree angle mode, multiplies
expression1
by
180/
p
. In Radian angle mode, returns
expression1
unchanged.
This function gives you a way to use a radian angle
while in Degree mode. (In Degree angle mode,
sin()
,
cos()
,
tan()
, and polar-to-rectangular
conversions expect the angle argument to be in
degrees.)
Hint: Use
ô
if you want to force radians in a function
or program definition regardless of the mode that
prevails when the function or program is used.
