COMBITRONIC: N/A
DETAILED DESCRIPTION:
The DFS(value) command allows the creation of a 32-bit value in IEEE-754 format. This allows
export of floating-point values to external systems. This format may be needed for
interchange.
The 32-bit value output by this function is not the integer rounded off from the input. It is an
encoded number that includes the exponent of the floating point value. The output of this
function does not have any usefulness within the SmartMotor programming language.
EXAMPLE:
af[0]=(a+b)/3.0 'Create a floating-point result.
al[0]=DFS(af[0]) 'Dump the IEEE-754 32-bit representation
'into al[0].
PRINT(#ab[0],#ab[1],#ab[2],#ab[3]) 'Print the 4 bytes (32-bits)
'of this result to the serial port for the
'host PLCto interpret.
