Field Detail

ZERO_DEC

public static final NumberFormat ZERO_DEC

A NumberFormat for zero places after the decimal. Used a lot, so might as well just define it once.

ONE_DEC

public static final NumberFormat ONE_DEC

A NumberFormat for one place after the decimal. Used a lot, so might as well just define it once.

TWO_DEC

public static final NumberFormat TWO_DEC

A NumberFormat for two places after the decimal. Used a lot, so might as well just define it once.

TEN_DEC

public static final NumberFormat TEN_DEC

A NumberFormat for ten places after the decimal. Used a lot, so might as well just define it once.

numOfSecondPerHour

public static final int numOfSecondPerHour

The number of second per hour
