1 Find the floor value of a positive decimal
In this example,
- We define a double
num
with a value of3.14
. - We call the
floorToDouble()
method onnum
to find its floor value. - We print the result to standard output.
Dart Program
void main() {
double num = 3.14;
double floorValue = num.floorToDouble();
print('Floor value of 3.14: $floorValue');
}
Output
Floor value of 3.14: 3
2 Find the floor value of a negative decimal
In this example,
- We define a double
num
with a value of-5.6
. - We call the
floorToDouble()
method onnum
to find its floor value. - We print the result to standard output.
Dart Program
void main() {
double num = -5.6;
double floorValue = num.floorToDouble();
print('Floor value of -5.6: $floorValue');
}
Output
Floor value of -5.6: -6
3 Find the floor value of a whole number
In this example,
- We define a double
num
with a value of10.0
. - We call the
floorToDouble()
method onnum
to find its floor value. - We print the result to standard output.
Dart Program
void main() {
double num = 10.0;
double floorValue = num.floorToDouble();
print('Floor value of 10.0: $floorValue');
}
