Description

The list of methods to do Float Number Round are organized into topic(s).

Method

intround(final float a)
Round a 
return (int) (a + Math.signum(a) * 0.5f);
intround(final float f)
round 
return (int) (f > 0 ? f + 0.5F : f - 0.5F);
intround(final float val)
round 
return floor(val + 0.5f);
intround(final float value)
round 
return (int) (value + (0.5f * Math.signum(value)));
floatround(final float x, final float roundFactor)
Computes a rounded value for the given rounding factor. 
return (float) Math.round(x * roundFactor) / roundFactor;
intround(float a)
Rounds the number to the closest integer 
return Math.round(a);
floatround(float amount, int cent)
round 
if (cent <= 0) {
    throw new IllegalArgumentException("cent must be greater than 0");
int roundAmount = Math.round(amount * 100.0f);
int x = roundAmount % cent;
int discount = 0;
if (x > cent / 2.0f) {
    discount = cent - x;
...
intround(float axisValue)
round 
if (Math.abs(axisValue) < 0.4f) {
    return 0;
return (int) Math.signum((int) (100 * axisValue));
intround(float d)
Ends up being a bit faster than Math#round(float) . 
return (int) (d + (d < 0.0f ? -0.5f : 0.5f));
floatround(float f, int dp)
round 
float pow = (float) Math.pow(10, dp);
float round = Math.round(f * pow);
return round / pow;
