This function gives you a way to use a gradian
angle while in the Degree or Radian modes.
In Radian angle mode, multiplies
expression
by
p/200. In Degree angle mode, multiplies
expression 1 by g/100.
In Gradian mode, returns expression1 unchanged.
In Degree, Gradian or Radian mode:

In Degree angle mode, multiplies
expression1
by
180/p. In Radian angle mode, returns
expression1
unchanged. In Gradian mode, multiplies
expression1
by 200/p.
This function gives you a way to use a radian
angle while in Degree and Gradian mode.
Hint: Use ôif you want to force radians in a
function or program definition regardless of the
mode that prevails when the function or program
is used.
