2.70 Pragma Float_Representation ¶

Syntax:

pragma Float_Representation (FLOAT_REP[, float_type_LOCAL_NAME]);

FLOAT_REP ::= VAX_Float | IEEE_Float

In the one argument form, this pragma is a configuration pragma which allows control over the internal representation chosen for the predefined floating point types declared in the packages Standard and System. This pragma is only provided for compatibility and has no effect.

The two argument form specifies the representation to be used for the specified floating-point type. The argument must be IEEE_Float to specify the use of IEEE format, as follows:

• For a digits value of 6, 32-bit IEEE short format will be used.
• For a digits value of 15, 64-bit IEEE long format will be used.
• No other value of digits is permitted.
