Argument

string

String value to convert.

Code Sample Example

This example reads a column of 6 values then converts the values to floating point values and then adds the ir values to the

&total variable. The total value is subsequently converted back to a string and the result is printed.

Example

define(&total,measure,0.0)

define(&x,integer,0)

for(&x,1,1,6)

set(&total,&total+strtofloat(@(&x,10,18)))

endfor()

show(floattostr(&total))

Sub (function)

Subtracts one expression from another. This is the functional equivalent of the - operator.

Syntax

sub( expression, expression2 ) integer, measure, currency value

Arguments

expression1, expression2

Integer, measure or currency values. Both expressions must be the same type. The returned value is set according to the type

of the parameters.

Code Sample Example

Example 1 and Example 2 illustrates both ways of subtracting numbers.

Example 1

show(inttostr(2-2))

Example 2
