1115 Returns the binary mantissa and exponent of v, i.e. <code>v == mantissa * 2 ^ exponent</code>.
1117 The mantissa is always between 0.5 (inclusive) and 1.0 (exclusive).
1214 Returns the base two exponent of a value, where the mantissa is between
1219 Because of the difference in mantissa, this number is one less than is returned by @frexp().
