1.2 List of High-level Instructions
Operand Function overview
Determines the absolute values of the real
S, D numbers stored in [S], and stores them in
[D].
Converts the single-precision floating point
real number stored in the area starting with
S, D
[S] to a double-precision floating point real
number.
Converts the double-precision floating point
real number stored in the area starting with
S, D
[S] to a single-precision floating point real
number.
Separates the floating point real number
S, D1, data stored in the area starting with [S] into
D2 mantissa and exponent according to the
operation unit [i].
Combines the data of mantissa and
S1, S2, exponent stored in the areas starting with
D [S1] and [S2] according to the operation
unit [i].
Converts the integer data stored in [S] to
S, D single-precision floating point real number
data, and stores it in [D].
Converts [S] (signed 32-bit integer data) to
S, D
real number data, and stores it in [D].
Converts the single-precision floating point
real numbers stored in [S] to integers
S, D
(maximum value cannot be exceeded), and
stores them in [D].
