F315_COS

The cosine of an angle data (units are radians) specified by s is calculated and the result stored in d.

Parameters

Input

s (REAL)

Real number angle data.

Output

d (REAL)

32-bit area for result (destination).

Remarks

• The accuracy of the calculation decreases as the absolute value of the angle data specified in s increases. We recommend that angle data be set within the following range:-2p (radians) £ [s] £ 2p (radians)

• F315_COS cannot be programmed in the interrupt program.

• Instead of using F315_COS, you can use variables of the type REAL with the more flexible instruction COS.

Error flags

sys_bIsOperationErrorHold (turns to TRUE and remains TRUE)

• if data other than real number data is specified in s.

• if the absolute value of s is ³ 52707176.

sys_bIsOperationErrorNonHold (turns to TRUE for one scan)

• if data other than real number data is specified in s.

• if the absolute value of s is ³ 52707176.

sys_bIsEqual (turns to TRUE and remains TRUE)

if the result of processing is recognized as "0".

sys_bIsCarry (turns to TRUE for one scan)

if the result is overflowed.
