Conversion from floating-point data to character string data
ESTR(P)
*1 Applicable for the Universal model QCPU, LCPU.
Processing details
• Converts the 32-bit floating decimal point data designated by (S1) to a character string according to the display designation
specified by (S2), and stores the result into the area starting from the device number designated by (D).
• The post-conversion data differs depending on the display designation designated by (S2).
• When an input value is set using a programming tool, a rounding error may occur. For precautions, refer to Page 89
Precautions.
• Basic model QCPU: The serial number (first five digits) is "04122" or later.
(S1): 32-bit floating decimal point data to be converted or head number of the devices where the data is stored (real number)
(S2): Head number of the devices where display designation for the numerical value to be converted is stored (BIN 16 bits)
(D): Head number of the devices where the converted character string will be stored (character string)
