Instance Method Details
abs() as Lang.Float
Get the absolute value of a Float.
format(format as Lang.String) as Lang.String
Format a Float using a formatting String.
The formatting string is similar to that available in printf from the
C stdio library, though the length option is not available:
"%[flags][width][.precision]specifier"
- specifiers
-
-
d or i - signed decimal integer
-
e - scientific notation (mantissa/exponent) using 'e' character
-
E - scientific notation (mantissa/exponent) using 'E' character
-
f - decimal floating point
-
o - signed octal
-
u - unsigned decimal integer
-
x - unsigned hexadecimal integer
-
X - unsigned hexadecimal integer (capital letters)
-
- flags
-
-
+ - Prepends the result with a plus or minus sign ('+' or '-'), including positive numbers. By default, only negative numbers are preceded with a '-' sign.
-
0 - Left-pads the number with zeros (0) instead of spaces, where padding is specified (see width sub-specifier).

toDouble() as Lang.Double
Convert a Float to a Double.
toFloat() as Lang.Float
Convert a Float to a Float.
toLong() as Lang.Long
Convert a Float to a Long.
toNumber() as Lang.Number
