DETAILED DESCRIPTION:
The LFS command is used to get the float value from 32-bit IEEE-754 format.
It allows the import of floating-point values from external systems — this format may be
needed for interchange.
The 32-bit value input by this function is not a normal integer value. It is an encoded number
that includes the exponent of the floating-point value.
NOTE: The input of this function does not have any usefulness within the
SmartMotor programming language.
The output of this function is a floating-point value that can be used in a formula. The output of
LFS() is directed to DFS(). For details on DFS(), see DFS(value) on page 387.
EXAMPLE:
al[0]=1162934955 '4 byte value in IEEE-754 format
af[0]=LFS(al[0]) 'Convert from IEEE-754 to float
Raf[0] 'Report value of float
Program output is:
3343.666748046
