The positive or negative sign:
the 20H or 2BH represents positive;
the 2DH represents negative.
The ineffective bytes
(space 20H and zero
30H) will be ignored
Only 6 digits will be taken, discards
the rest (the 7 is useless)
S : the head ID of the character string to be converted

This instruction will use the following ASCII conversion table:
S
This instruction uses a string started from the to perform the BIN floating point number conversion, then stores
the result into the device . The format of the source string can either use the decimal notation or the exponential
notation.
