Calculating the tangent of single-precision real number
TAN(P)/DTAN(P)
These instructions calculate the tangent of the angle specified by (s), and store the operation result in the device specified by
(d).
The TAN(P) instructions can also be used as DTAN(P).
*1 The TAN instruction is not supported by the ST language. Use TAN of the standard function.

Processing details
• These instructions calculate the tangent of the angle specified by (s), and store the operation result in the device specified
by (d).
• Set the angle data in radians (angle

180).
• The table below shows the related devices.
Precautions
When the angle specified by (s) is

/2 radian or (3/2)

radian, no error occurs because an operation error occurs in a radian
value.

SM700 Carry The absolute value of the operation result

2
128
The value of (d) is the maximum value (2
128
) of 32-bit real
numbers and the carry flag SM700 turns on.
SM8020 Zero The operation result is true "0".
(The mantissa part is "0"). The zero flag SM8020 turns on.
SM8021 Borrow The absolute value of the operation result < 2
-126
The value of (d) is the minimum value (2
-126
) of 32-bit real
numbers and the borrow flag SM8021 turns on.
SM8022 Carry The absolute value of the operation result

2
128
The value of (d) is the maximum value (2
128
) of 32-bit real
numbers and the carry flag SM8022 turns on.
