    Floating point numbers are only stored as fullword or doubleword values on older models. On the 360/85 [9] and 360/195 [10] there are also extended precision floating point numbers stored as quadwords. For all three formats, bit 0 is a sign and bits 0-7 are a characteristic (exponent, biased by 64). Bits 8-31 (8-63) are a hexadecimal fraction.
