Lua reference description: Returns
e such that
x = m2e,
e is an integer and the absolute value of
m is in the range ((0.5, 1) (or zero when x is zero).
Used to split the number value into a normalized fraction and an exponent. Two values are returned: the first is a multiplier in the range
1/2 (inclusive) to
1 (exclusive) and the second is an integer exponent.
The result is such that
x = m*2^e.
