Floating-point numbers are designated by the following pre-declared type identifiers:

Single precision float32 4 bytes IEEE-754 binary floating point, approximately 6 digits of precision.
Double precision float64, 15 digits of precision.
Complex: complex64 and complex128.

There is no float, as in the integer case, we must explicitly provide the precision.

Uninitialized variable value: +0.000000e+000

Decimals:

var x float = 123.45

Scientific notation, with exponent in base 10:

var x float = 1.23e3

var z complex128 = complex(2, 3)
