$DBLB string function

Syntax

$DBLB (value)

Function

Return an 8-byte string containing the binary representation of a real value in double-precision IEEE floating-point format.

Parameter

value Real-valued expression, the value of which is converted to its IEEE floating-point binary representation.

Details

A real value is converted to its binary representation using the IEEE double-precision standard floating-point format. This 64-bit value is packed as eight successive 8-bit characters in a string. See the DBLB real-valued function for a more detailed description of IEEE floating-point format.

The main use of this function is to convert a double-precision real value to its binary representation in an output record of a data file.

Example
     $DBLB(1.215)
Returns a character string equivalent to:
$CHR(^H3F)+$CHR(^H3F)+$CHR(^H70)+
$CHR(^HA3)+$CHR(^HD7)+$CHR(^H0A)+$CHR(^H3D)+$CHR(^H71)
