角度->弧度

onej

ANGLE '(10 10) '(30 30))
Result : 0.785398 (等於45度)

结果是弧度，有没什么函数可以转化成角度？ 互逆的函数呢？（角度->弧度）

(/ (* ang 180) pi)

Return Values

A real value, if successful; otherwise nil.

The angtof and angtos functions are complementary: if you pass angtof a string created by angtos, angtof is guaranteed to return a valid value, and vice versa (assuming the unit values match).

Examples

Command: (angtof "45.0000")

0.785398

Command: (angtof "45.0000" 3)

1.0177

或

Examples

Command: (angtos 0.785398 0 4)

"45.0000"

Command: (angtos -0.785398 0 4)

"315.0000"

Command: (angtos -0.785398 4)

"S 45d E"
