Acceptedcharacters:numbers, decimal point markers (period or comma), sign indicators (-),spaces (e.g., as thousands separator, 5 000), “E” or“e” (used in scientific notation). NOTE: For scientificnotation, a period MUST be used as the decimal point marker.Complex numbers should be in the form (a + bi) where “a” and“b” need to have explicitly stated values.For example: {1+1i} is valid whereas {1+i} is not. {0+9i} is valid whereas{9i} is not.
