extracts the integer part and converts it to an extended-precision floating-point number.
Stores the result in the destination floating-point data register. The integer part is
extracted by rounding the extended-precision number to an integer using the round-to-
zero mode, regardless of the rounding mode selected in the floating-point control
register mode control byte (making it useful for FORTRAN assignments). Thus, the
integer part returned is the number that is to the left of the radix point when the
exponent is zero. For example, the integer part of 137.57 is 137.0; the integer part of
0.1245 x 102 is 12.0. Note that the result of this operation is a floating-point number.
