or double or single
(double > single)
Dim cByte as Byte 'declare cByte as 1 byte numeric value ranging from 0 to 255. Used in bit/byte manipulations.
Dim Ip as Integer 'declares "Ip" as a numeric variable of 2 bytes whose values can range between -32768 to 32767
' use Integers for loop variables, counters and small table indexes.
Dim Lval as Long 'declares "Lval" as a whole number of 4 bytes with range between -2,147,483,648 to 2,147,483,647
' use Longs for indexes into large tables, file i/o, and other VB counters;
Dim Bucks as Currency 'declares "Bucks" as a numeric variable of 10 bytes with high calculation accuracy
' which ranges from -922,337,203,685,477.5808 to 922,337,203,685,477.5807.
' Use this data type for calculations involving money and fixed decimal point accuracy.
' Currency calculations are about as fast as longs.
Dim dontUse as Single 'declares "dontUse" as a single precision floating point variable.
' Use Double rather than Single except where demanded by VB/Windows API;
' Double is much more accurate and even runs about 10-20% faster than Single.
Dim Realone as Double 'declares "Realone" as a double precision floating point variable of 8 bytes which can range from
' -1.79769313486232E308 to -4.94065645841247E-324 for negative values;
