ATN

Numeric Fun ction

SYNTAX: n = ATN(m)

PURPOSE: To return the arctangent of m.

REMARK S: The result, n, of the ATN function is a value in radians in the range of – PI/2 to PI/2, wher e PI =

3.141593. The expr ession may be integer , bu t the evaluation is alw ays performed in floating point.

To obtain the tangent of m when m is in degrees, use TAN (m*B180).

Trigonometr ic functions ar e computed as a power ser ies in CA MBASIC. Calculations are done in

single precision floating point to seven digits of precision. Since the power series is an

approximation, the result will be accurate to four to six digits, depending upon the value of m.

RELATED: COS, SIN, TAN

EXAMPLE: 10 PI = 3.141593

20 RADIANS = ATN(1)

30 DEGREES = RADIANS * 180 / PI

40 PRINT RADIANS,DEGREES
