float¶

Float built-in type.

Description¶

Float built-in type.

Methods¶

float	float ( bool from )
float	float ( int from )
float	float ( String from )

Method Descriptions¶

float float ( bool from )

Cast a bool value to a floating-point value, float(true) will be equal to 1.0 and float(false) will be equal to 0.0.

float float ( int from )

Cast an int value to a floating-point value, float(1) will be equal to 1.0.

float float ( String from )

Cast a String value to a floating-point value. This method accepts float value strings like "1.23" and exponential notation strings for its parameter so calling float("1e3") will return 1000.0 and calling float("1e-3") will return 0.001. Calling this method with an invalid float string will return 0. This method stops parsing at the first invalid character and will return the parsed result so far, so calling float("1a3") will return 1 while calling float("1e3a2") will return 1000.0.
