Floating point number:

# fractional
flt1 = +1.0
flt2 = 3.1415
flt3 = -0.01

# exponent
flt4 = 5e+22
flt5 = 1e6
flt6 = -2E-2

# both
flt7 = 6.626e-34

# infinity
sf1 = inf  # positive infinity
sf2 = +inf # positive infinity
sf3 = -inf # negative infinity

# not a number
sf4 = nan  # actual sNaN/qNaN encoding is implementation specific
sf5 = +nan # same as `nan`
sf6 = -nan # same as `nan`
