[label:]
.double
absolute-expression[, ... ]
[; comment]

[Function]

-

The .double directive tells the assembler to initialize 8-byte area.

-

The .double directive also tells the assembler to initialize a memory area in 8-byte units with the initial value(s) specified in the operand field.

[Description]

-

The value of the absolute expression is secured as a double-precision floating-point number. Consequently, the value of the expression must be between -1.7976931348623157e+308 and 1.7976931348623157e+308. In other cases, it is assumed as infinity with the same sign.

-

If the relocation attribute of the section is "BSS", then an error is output because the .double directive cannot be described.

-

Two or more absolute-expression may be specified within a statement line of the .double directive.
