com.softwaremining.wrappers.format.NumericFormatFloat

public final class NumericFormatFloat
extends AbstractNumericFormat

Used for representation of COMP_2 and COMP_4 variables. COMPUTATIONAL-4 or COMP-4 Specified for internal floating-point items (single precision). COMP-4 items are 4 bytes long. The sign is contained in the first bit of the leftmost byte and the exponent is contained in the remaining 7 bits. The last 3 bytes contain the mantissa.
