FXCPU Structured Programming Manual
[Basic & Applied Instruction]
b) In the case of exponential type
• To be converted as positive value when "2BH" (+) is specified by the sign or the sign is omitted in the
decimal point type. To be converted as negative value when "2DH" (-) is specified by the sign.
• To be converted as positive value when "2BH" (+) is specified in the exponential part sign or the sign is
omitted in the exponential type. To be converted as negative value when "2DH" (-) is specified in the
exponential part sign.
• When "20H" (space) or "30H" (0) is present among the numeric values except for the first "0" in the
character string specified by , "20H" or "30H" is ignored in the converting operation.
• When "30H" (0) is present between "E" and the numeric value in the character string in the exponential
type, "30H" is ignored in the converting operation.
• The character string can be set in a maximum of 24 characters.
In the character string, "20H" (space) or "30H" (0) is counted as one character.
