Summary of integer to float in Java

First, convert the integer to type int, in the forced-to-float type

Example: integer str = new integer (20);

int i = Str.intvalue ();

Float rr = (float) i;

Output Result: 20.0

Two. Convert the integer type to type string and convert to float type

Example: Integer str = 2056;

String format = new BigDecimal (string.valueof (str)). toString ();

Float rr = float.valueof (format);

Output is 20.0

Three. BigDecimal Turn float

Example: BigDecimal tt = new BigDecimal (+);

float KK = Tt.floatvalue ();

Output results: 50.0

Above all I personally test, if not meet, please carefully check
