x

flonum

Returns the bits comprising x as an integer. A convenient shortcut for composing integer-bytes->integer with real->floating-point-bytes (Note: neither of these is in CHICKEN).

Examples:

> (number->string (flonum->bit-field -inf.0) 16)
"fff0000000000000"
> (number->string (flonum->bit-field +inf.0) 16)
"7ff0000000000000"
> (number->string (flonum->bit-field -0.0) 16)
"8000000000000000"
> (number->string (flonum->bit-field 0.0) 16)
"0"
> (number->string (flonum->bit-field -1.0) 16)
"bff0000000000000"
> (number->string (flonum->bit-field 1.0) 16)
"3ff0000000000000"
> (number->string (flonum->bit-field +nan.0) 16)
"7ff8000000000000"
