$TRANSB string function

Syntax

$TRANSB (transformation)

Function

Return a 48-byte string containing the binary representation of a transformation value.

Parameter

transformation Transformation variable or function (or compound transformation) that defines the value to be converted to a string value.

Details

This function converts the given transformation value to the binary representation of its twelve (internal) components. The twelve values defining the transformation are the components of a 3-by-4 transformation matrix, stored by column. Each of the twelve 32-bit values is packed as four successive 8-bit characters in a string, resulting in a total of 48 characters. (The IEEE single-precision standard floating-point format is used for the conversion. See the description of the FLTB real-valued function for details of the IEEE floating-point format.)

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