(3) Floating-point NR3 transfer
A decimal numeric having an exponent, i.e., a real number (NR3) represented in floating-point notation, is
transferred. The syntactical chart consists of a mantissa part and an exponent part. The exponent part is
represented in integer and floating-point notation to indicate precision of the numeric. The exponent part
begins with E. On the right of E is a number to the power of 10.

(Exponent part)
● E indicates power of 10. It indicates the beginning of the exponent part.
● E may be either an uppercase or lowercase character. → 1.234E + 12, 1.234e + 12
● A space may be written before or after E/e. → 1.234 ∆E∆ + 12
● If the sign is +, it may be omitted in mantissa and exponent parts. → + 1.234E + 4, 1.234E4
● The numeric in the exponent part cannot be omitted. → –1E2, –E2 (×), –.E2 (×)
