Declaration:
void
push_radians
(EStackIndex
i
)
Category(ies):
Math
Description:
Converts the input value, interpreted as radians, to the currently selected
angle measure.
Inputs:
i
— EStackIndex of internal tokenized radians value.
Outputs:
Pushes the internal tokenized form of the result of converting the specified
radians to the currently selected angle measure — radians or decimal
degrees.
Assumptions:
None
Side Effects:
May cause estack expansion, heap compression, or throw errors.
Availability:
On AMS 2.00 and higher.

Example:
If the current angle setting is RADIANS and i indexes
π
/2, then
push_radians (i);
pushes the value
π
/2 onto the estack.
If the current angle setting is DEGREES and i indexes
π
/2, then
push_radians (i);
pushes the value 90 which is the equivalent number of degrees onto the estack.
