Overview
Floating-point numbers are designated by the following pre-declared type identifiers:
- Single precision
float324 bytes IEEE-754 binary floating point, approximately 6 digits of precision. - Double precision
float64, 15 digits of precision. - Complex:
complex64andcomplex128.
There is no float, as in the integer case, we must explicitly provide the precision.
Uninitialized variable value: +0.000000e+000
Floating-Point Literals
Decimals:
var x float = 123.45
Scientific notation, with exponent in base 10:
var x float = 1.23e3
