7 BASIC INSTRUCTIONS
7.5 Data Conversion Instructions
Converting single-precision real number to 32-bit signed binary
data
FLT2DINT(P)
These instructions convert the single-precision real number in the device specified by (s) to 32-bit signed binary data, and
store the converted data in the device specified by (d). After conversion, the digits after the decimal point of the single-
precision real number, specified with (s), are truncated.
*1 Supported by engineering tool version "1.035M" and later.
