19.4 Floating Point Real Number Operation

19.4 Floating Point Real Number Operation
For floating point real number operations, the outcome of the operation with an infinitesimal or
infinite operation result or with an infinitesimal or infinite input value is as follows.
■
Infinitesimal operation result
Instru
SIN COS TAN
ction
Input
- -
value
(Note 1) Instructions indicated with "-" do not result in an infinitesimal value.
(Note 2) Instructions indicated with ● result in an operation error.
(Note 3) An operation error is output if the input value is out of the available range.
■
Infinite operation result
Instru
SIN COS TAN
ction
Input
- -
value
(Note 1) Instructions indicated with "-" do not result in an infinite value.
(Note 2) Instructions indicated with ● result in an operation error.
(Note 3) An operation error is output if the input value is out of the available range.
■
Infinitesimal (-∞) input value
Instru
SIN COS TAN
ction
Input
nan nan
value
(Note 1) Instructions indicated with "nan" result in an indefinite value.
(Note 2) Instructions indicated with ● result in an operation error.
(Note 3) An operation error is output if the input value is out of the available range.
■
Infinite (+∞) input value
Instru
SIN COS TAN
ction
Input
nan nan
value
(Note 1) Instructions indicated with "nan" result in an indefinite value.
(Note 2) Instructions indicated with ● result in an operation error.
(Note 3) An operation error is output if the input value is out of the available range.
