| - | |||
| - | ==== Description ==== | ||
| - | Computes the tangent of angle in radians. | ||
| - | |||
| - | ==== Note ==== | ||
| - | The tan function does not produce an exact result. | ||
| - | |||
| - | ==== Example ==== | ||
| - | < | ||
| - | clg | ||
| - | color black | ||
| - | # draw a line across the graphic output | ||
| - | line 0, | ||
| - | # where do we start | ||
| - | lastx = 0 | ||
| - | lasty = tan(0) * 50 + 150 | ||
| - | # now step across the line and draw | ||
| - | for x = 0 to 300 step 5 | ||
| - | angle = x / 300 * 2 * pi | ||
| - | y = tan(angle) * 50 + 150 | ||
| - | line lastx, lasty, x, y | ||
| - | lastx = x | ||
| - | lasty = y | ||
