3.14159265358979e+000 + Positive/Negative format with +, -, and blank characters displayed for positive, negative, and zero elements. Long engineering notation (exponent is a multiple of 3) with 15 significant digits. longe: All floating-point output uses exponential format. Short engineering notation (exponent is a multiple of 3) with 4 digits after the decimal point. ( − 1 ) b 31 × 2 ( b 30 b 29 … b 23 ) 2 − 127 × ( 1. shorte: All floating-point output uses exponential format with four decimal places, such as 4.2000e+00. The real value assumed by a given 32-bit binar圓2 data with a given sign, biased exponent e (the 8-bit unsigned integer), and a 23-bit fraction is Thus only 23 fraction bits of the significand appear in the memory format, but the total precision is 24 bits (equivalent to log 10(2 24) ≈ 7.225 decimal digits). The true significand includes 23 fraction bits to the right of the binary point and an implicit leading bit (to the left of the binary point) with value 1, unless the exponent is stored with all zeros. The sprintf command seems to print out exponential notation when decimal notation is requested (second and third. there is no type in format that generally tells MATLAB to use such a format. Exponents range from −126 to +127 because exponents of −127 (all 0s) and +128 (all 1s) are reserved for special numbers. The exponent is an 8-bit unsigned integer from 0 to 255, in biased form: an exponent value of 127 represents the actual zero. The sign bit determines the sign of the number, which is the sign of the significand as well. If an IEEE 754 single-precision number is converted to a decimal string with at least 9 significant digits, and then converted back to single-precision representation, the final result must match the original number. If a decimal string with at most 6 significant digits is converted to the IEEE 754 single-precision format, giving a normal number, and then converted back to a decimal string with the same number of digits, the final result should match the original string. This gives from 6 to 9 significant decimal digits precision.
