The floating point formats generated by directives are these.

|

|
|
then then <code>double</code> directive generates <code>double</code> precision
|
||
|
|
(64-bit) floating point constants, otherwise it generates
|
||
|
|
<code>single</code> precision (32-bit) floating point constants. To force
|
||
|
|
the generation of 64-bit floating point constants used the <code>dc.d</code>
|
||
|
|
directive instead.
