List of round() Examples

Examples of round()

client.net.sf.saxon.ce.value.NumericValue.round()
Implement the XPath round() function @return a value, of the same type as that supplied, rounded towards thenearest whole number (0.5 rounded up)
com.foundationdb.server.types.common.BigDecimalWrapper.round()
java.math.BigDecimal.round()
Returns a {@code BigDecimal} rounded according to the{@code MathContext} settings. If the precision setting is 0 thenno rounding takes place.
The effect of this method is identical to that of the {@link #plus(MathContext)} method. @param mc the context to use. @return a {@code BigDecimal} rounded according to the {@code MathContext} settings. @throws ArithmeticException if the rounding mode is{@code UNNECESSARY} and the{@code BigDecimal} operation would require rounding. @see #plus(MathContext) @since 1.5
nav.util.math.NumUtil.Round()
Rounds a number. @param Rval number to be rounded @param Rpl number of decimal places @return rounded number @since 0.1
net.algart.math.patterns.Pattern.round()
Returns this pattern, every point of which is rounded to the nearest integer point. The result is always ordinary integer pattern (see the {@link Pattern comments to this interface}, section "Uniform-grid patterns").
More precisely, the resulting pattern:
1. consists of all points, obtained from all points of this pattern by rounding by the call point. {@link Point#toRoundedPoint() toRoundedPoint()}. {@link IPoint#toPoint() toPoint()};
2. has zero origin {@link UniformGridPattern#originOfGrid()}=(0,0,...,0) and unit steps {@link UniformGridPattern#stepsOfGrid()}={1,1,..,1}.
Note: the number of points in the result can be less than {@link #pointCount()}, because some real points can be rounded to the same integer points.

Warning! If this object is not {@link DirectPointSetPattern}and is not {@link RectangularPattern}, this method can work slowly for some large patterns: the required time can be O(N), where N is the number of points. In these cases, this method can also throw {@link TooManyPointsInPatternError}or OutOfMemoryError. The situation is like in {@link #points()} and {@link #roundedPoints()} method.
There is a guarantee, that if this object implements {@link DirectPointSetPattern} interface,then this method requires not greater than O(N) operations and memory (N= {@link #pointCount() pointCount()}) and never throws {@link TooManyPointsInPatternError}.
There is a guarantee, that if this object implements {@link RectangularPattern} interface,then this method works quickly (O(1) operations) and without exceptions. It is an important difference from {@link #points()} and {@link #roundedPoints()} method.
The theorem I, described in the {@link Pattern comments to this interface}, section "Coordinate restrictions", provides a guarantee that this method never throws {@link TooLargePatternCoordinatesException}. @return the integer pattern, geometrically nearest to this one. @throws TooManyPointsInPatternError if this pattern is not {@link DirectPointSetPattern} andnot {@link RectangularPattern} and if, at the same time, the numberof points is greater than Integer.MAX_VALUE or, in some rare situations, is near this limit (OutOfMemoryError can be also thrown instead of this exception).
net.sf.saxon.value.NumericValue.round()
Implement the XPath round() function @return a value, of the same type as that supplied, rounded towards thenearest whole number (0.5 rounded up)
org.apache.velocity.tools.generic.MathTool.round()
Rounds a number to the nearest whole Integer @param num the number to round @return the number rounded to the nearest whole Integeror null if it's invalid @see java.lang.Math#rint(double)
org.bouncycastle.pqc.math.ntru.polynomial.BigDecimalPolynomial.round()
Rounds all coefficients to the nearest integer. @return a new polynomial with BigInteger coefficients
org.elasticsearch.common.rounding.TimeZoneRounding.round()
org.exist.xquery.value.NumericValue.round()
org.hsqldb.types.DateTimeType.round()
org.hsqldb.types.Type.round()
org.jExigo.FixedDecimalNumber.round()
rounds to the least number of significant digits @param leastSignificantDigits @throws Exception - most likely passed a negative number
org.pdf4j.saxon.value.NumericValue.round()
Implement the XPath round() function @return a value, of the same type as that supplied, rounded towards thenearest whole number (0.5 rounded up)
