F321_EXP

Redundant instruction

Anmerkung

This is a redundant instruction. It is replaced by: EXP

The exponent (EXP) is calculated from the real number data specified in s, and the result is stored in d. The calculation is performed with the exponent base (e) equal to 2.718282 (Euler’s number).

Parameters

Input

s (REAL): Real number input data.

Output

d (REAL): 32-bit area for result (destination).

Remarks

F321_EXP is the reverse function of F320_LN.
F321_EXP cannot be programmed in the interrupt program.
Instead of using F321_EXP, you can use variables of the type REAL with the more flexible instruction .

Error flags

sys_bIsOperationErrorHold (turns to TRUE and remains TRUE)

if data other than real number data is specified in s.
if s is not greater than zero.

sys_bIsOperationErrorNonHold (turns to TRUE for one scan)

if data other than real number data is specified in s.
if s is not greater than zero.

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.
