Converting single-precision real number to character string
ESTR(P)/DESTR(P)
These instructions convert the single-precision real number data stored in the device specified by (s1) into a character string
according to the display specification stored in the device specified by (s2) and later, and store the string in the device
specified by (d) and later.
The ESTR(P) instructions can also be used as DESTR(P).
■Descriptions, ranges, and data types
■Applicable devices
*1 T, ST, C cannot be used.
• These instructions convert the single-precision real number data stored in the device specified by (s1) into a character
string according to the display specification stored in the device specified by (s2) and later, and store the string in the device
specified by (d) and later. A real number can be directly specified as (s1).
• The data after conversion varies depending on the display specification stored in (s2).
