TANH: Binary oating point TANH operation
◆
Overview
The TANH instruction calculates the tanh of a binary oating-point number. The calculation formula is Tanh
= (e
s
– e

Function
The tanh of a binary oating-point number is calculated. The calculation formula is Tanh = (e
s
– e
-s
)/(e
s
+ e
-s
).
Example:
M10
ǒDTANH D0 D2Ǔ
S D
M11
When M10 = ON, the tanh of the binary floating-point number in
(D1, D0) is calculated. The result is stored in (D3, D2).
