stores 32-bit binary data converted from a character string with the decimal point ignored.
In the character string located after
, "space" (20H) or "0" (30H) put between the sign and the first
number except "0" is ignored in conversion into 32-bit binary data.

Errors
An operation error is caused in the following cases; The error flag M8067 turns ON, and the error code is
stored in D8067.
• When the number of characters of a character string to be converted (
and later) is outside the
following range (error code: K6706)
• When the number of characters of the decimal part of a character string to be converted (
and later)
is outside the following range (error code: K6706)
• When the relationship between the number of all characters of a character string to be converted (
and later) and the number of characters of the decimal part does not satisfy the following (error code:
K6706)

≥
Number of characters of decimal part
• When the sign is set to any ASCII code other than "space" (20H) and "-" (2DH) (error code: K6706)
