Accepted characters: 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 scientific notation, 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. The nominal rate of interest is currently 6.0%. What is the real rate of interest if the expected inflation rate is 4.0%? (Enter a number in decimal format using three decimal places, rounded to the nearest third decimal: e.g., if you calculate 0.0258, enter 0.026)
