Double-precision Floating-point Instructions
îš„ Ladder Program for the Single-precision Calculation
1. This program section converts the BCD data to single-
precision floating-point data (32 bits, IEEE754-for-
mat).
• The BIN(023) instructions convert the BCD data to
binary and the FLT(452) instructions convert the
binary data to single-precision floating-point data.
• The floating-point data for the angle θ is output to
D200 and D201.
• RAD(458) converts the angle data in D200 and
D201 to radians.
• The floating-point data for the radius r is output to
D1200 and D1201.
2. This program section calculates the sin θ and the cos
θ as single-precision floating-point values.
• The value for cos θ is output to D300 and D301.
• The value for sin θ is output to D400 and D401.
3. This program section calculates x (r × cos θ) and y (r ×
sin θ).
• The value for x (r × cos θ) is output to D10000 and
D10001.
• The value for y (r × sin θ) is output to D20000 and
D20001.
