List of signum() Examples

Examples of signum()

cc.redberry.core.transformations.factor.jasfactor.edu.jas.poly.ExpVector.signum()
ExpVector signum. @return 0 if this is zero, -1 if some entry is negative, 1 if no entry isnegative and at least one entry is positive.
com.ericsson.otp.erlang.OtpErlangLong.signum()
Return the signum function of this object. @return -1, 0 or 1 as the value is negative, zero or positive.
com.vividsolutions.jts.math.DD.signum()
Returns an integer indicating the sign of this value.
- if this value is > 0, returns 1
- if this value is < 0, returns -1
- if this value is = 0, returns 0
- if this value is NaN, returns 0
@return an integer indicating the sign of this value
com.wesabe.api.util.money.Money.signum()
Returns the signum function of this {@link Money}. @return {@code -1}, {@code 0}, or {@code 1} as the value of this{@link Money} is negative, zero, or positive.
com.zaranux.client.crypto.util.BigInteger.signum()
java.math.BigDecimal.signum()
Returns the signum function of this {@code BigDecimal}. @return -1, 0, or 1 as the value of this {@code BigDecimal} is negative, zero, or positive.
java.math.BigInteger.signum()
Returns the signum function of this BigInteger. @return -1, 0 or 1 as the value of this BigInteger is negative, zero orpositive.
mikera.arrayz.INDArray.signum()
Calculates the signum of all elements of the array
net.sf.saxon.value.NumericValue.signum()
Determine whether the value is negative, zero, or positive @return -1 if negative, 0 if zero (including negative zero), +1 if positive, NaN if NaN
org.apache.hadoop.hive.common.type.HiveDecimal.signum()
Get the sign of the underlying decimal. @return 0 if the decimal is equal to 0, -1 if less than zero, and 1 if greater than 0
org.pdf4j.saxon.value.NumericValue.signum()
Determine whether the value is negative, zero, or positive @return -1 if negative, 0 if zero (including negative zero), +1 if positive, NaN if NaN
