Float

• The float type corresponds to IEEE 754-2008 64-bit binary (radix 2) floating point numbers.
• This is same as double in Java.
• No implicit conversions between int and float are allowed. Need to use <T> for explicit conversions.
• Literal uses the suffix f.

Sample

import ballerina/io;

public function main() {
    float f1 = 1.67;

    int i1 = 5;

    // Use `<T>` for explicit conversions.
    float f2 = f1 + <float>i1;
    io:println(f2);

    //Use ballerina/lang.float function.
    float f3 =f1.round();
    io:println(f3);   
}

Output
