18.5 FNC117 – EVAL / Character String to Floating Point Conversion
b) In the case of exponent format
• When "2BH (+)" is specified as the sign in the floating point format or when the sign is omitted, a character string is
converted into a positive value.
When "2DH (-)" is specified as the sign, a character string is converted into a negative value.
• When "2BH (+)" is specified as the sign in the exponent format or when the sign is omitted, a character string is
converted into a positive exponent.
When "2DH (-)" is specified as the sign, a character string is converted into a negative exponent.
• When "20H (space)" or "30H (0)" exists between numbers except the first "0" in a character string specified by
, "20H" or "30H" is ignored during conversion.
• When "30H (0)" exists between a number and "E" in a character string in the exponent format, "30H" is ignored
during conversion.
• A character string can consist of up to 24 characters.
"20H (space)" and "30H (0)" in a character string are counted as one character respectively.
