The FloatConverter class allows you to convert arbitrary values into float using extended conversion rules.
Description
The FloatConverter class allows you to convert arbitrary values into float using the following extended conversion rules:
- Strings are converted to float values
- DateTime: total number of milliseconds since unix epoch
- Boolean: 1 for true and 0 for false
Static methods
toFloat
Converts a value into a float or returns 0 when the conversion is not possible.
See DoubleConverter.toDouble
staticdouble toFloat(value)
- value: dynamic - value to convert.
- returns: double - float value or 0 when the conversion is not supported.
toFloatWithDefault
Converts a value into a float or returns a given default when the conversion is not possible.
See DoubleConverter.toDoubleWithDefault,
DoubleConverter.toNullableDouble
staticdouble toFloatWithDefault(value, double defaultValue)
- value: dynamic - value to convert.
- defaultValue: double - default value.
- returns: double - float value or default value when the conversion is not supported.
toNullableFloat
Converts a value into a float or returns null when the conversion is not possible.
See DoubleConverter.toNullableDouble
staticdouble? toNullableFloat(value)
- value: dynamic - value to convert.
- returns: double? - float value or null when the conversion is not supported.
Examples
var value1 = FloatConverter.toNullableFloat('ABC'); // Result: null
var value2 = FloatConverter.toNullableFloat('123.456'); // Result: 123.456
var value3 = FloatConverter.toNullableFloat(true); // Result: 1
var value4 = FloatConverter.toNullableFloat( Date()); // Result: current milliseconds
