18.17 FNC129 – INT / Floating Point to Integer Conversion
Outline
This instruction converts binary floating point data into a binary integer which is a normal data format inside PLCs
(binary floating point binary integer).
For program examples of floating point operations, refer to Section 12.10.
For handling of floating point, refer to Subsection 5.1.3.

2. Set data
3. Applicable devices
S: This function is supported only in FX3U/FX3UC PLCs.
Explanation of function and operation
1. 16-bit operation (INT and INTP)
Binary floating point stored in [ +1, ] is converted into a binary integer, and transferred to .
Instruction for inverse conversion
The inverse conversion is executed by FLT (FNC 49) instruction.
For FLT (FNC 49) instruction, refer to Section 12.10.
2. 32-bit operation (DINT and DINTP)
Binary floating point stored in [ +1, ] is converted into a binary integer, and transferred to [ +1,
].
Instruction for inverse conversion
The inverse conversion is executed by DFLT (FNC 49) instruction.
For FLT (FNC 49) instruction, refer to Section 12.10.
