Function
Binary oating-point numbers are converted to decimal equivalents.
Example:
The binary floating-point number in (D3, D2) is converted to a decimal
equivalent. The result is stored in (D11, D10).
For the binary floating-point number in (D3, D2), the real number
occupies 23 bits, the exponent occupies eight bits, and the sign
occupies one bit.
For the decimal floating-point number in (D11, D10), the exponent (D3)
and real number (D2) are expressed as D2 x 10
D3
in scientific notation.

The PLC uses only binary oating-point numbers for calculation. Convert binary oating-point numbers to
decimal equivalents for easy monitoring.
