DCOSH, DCOSHP: 6 steps
Operands:
S
: Source device (binary floating value)
D
: Operation result
Explanations:
1. COSH value =
（
e
s
+e
-s
）
/ 2. COSH instruction performs hyperbolic-cosine operation on
S
and stores the result in
D
2. F refers to floating point input. Be sure to add a decimal point when using it.
3. Only 32-bit instructions DCOSH and DCOSHP are applicable.
4. Flags:
OX O100
Zero flag M1808 M1968
Borrow flag M1809 M1969
Carry flag M1810 M1970
a) If the absolute value of the result exceeds the max floating point value, carry flag will be ON.
b) If the absolute value of the result is less than min. floating point value, borrow flag will be ON.
c) If the conversion result is 0, zero flag will be ON.
Program Example:
When X0 = ON, DCOSH instruction performs hyperbolic-cosine operation on the binary floating value in (D1, D0)
and stores the COSH value in (D11, D10) in binary floating format.
