Conversion into a string with a decimal number with 6 decimal places and a total
length of at least <m> characters. Where relevant, the decimal places are rounded-
off or filled with 0. Missing characters are filled up to the total length <m> using
spaces, left-justified.
Example:
N10 DEF REAL REAL_VAR=-1.23412345678EX+03
N20 DEF STRING[80] RESULT
N30 RESULT=SPRINT("CONTENT OF REAL_VAR:%15F",REAL_VAR)
Result: The character string "CONTENT OF REAL_VAR: xx-1234.123457" is
written to the string variable RESULT ("x" in the example represents spaces).
Conversion into a string with a decimal number with <n> decimal places. Where
relevant, the decimal places are rounded-off or filled with 0.
Example:
N10 DEF REAL REAL_VAR=-1.2345678EX+03
N20 DEF STRING[80] RESULT
N30 RESULT=SPRINT("CONTENT OF REAL_VAR:%.3F",REAL_VAR)
Result: The character string "CONTENT OF REAL_VAR:-1234.568" is written to
the string variable RESULT.
Conversion into a string with a decimal number with <n> decimal places and a total
length of at least <m> characters. Where relevant, the decimal places are rounded-
off or filled with 0. Missing characters are filled up to the total length <m> using
spaces, left-justified.
Example:
N10 DEF REAL REAL_VAR=-1.2341234567890EX+03
N20 DEF STRING[80] RESULT
N30 RESULT=SPRINT("CONTENT OF REAL_VAR:%10.2F",REAL_VAR)
Result: The character string "CONTENT OF REAL_VAR:xx-1234.12" is written to
the string variable RESULT ("x" in the example represents spaces).
Conversion into a string with a decimal number in the exponential representation.
The mantissa is saved, normalized with one pre-decimal place and 6 decimal
places. Where relevant, the decimal places are rounded-off or filled with 0. The
exponent starts with the keyword "EX". It is followed by the sign ("+" or "-") and a
two or three-digit number.
Example:
N10 DEF REAL REAL_VAR=-1234.567890
N20 DEF STRING[80] RESULT
N30 RESULT=SPRINT("CONTENT OF REAL_VAR:%E",REAL_VAR)
Result: The character string "CONTENT OF REAL_VAR:-1.234568EX+03" is
written to the string variable RESULT.

and a total length of at least <m> characters. The missing characters are filled with

Example:
N10 DEF REAL REAL_VAR=-1234.5
N20 DEF STRING[80] RESULT
N30 RESULT=SPRINT("CONTENT OF REAL_VAR:%20E",REAL_VAR)
Result: The character string "CONTENT OF REAL_VAR:xxxxxx-1.234500EX+03"
is written to the string variable RESULT ("x" in the example represents spaces).
