The NUMERIC() function converts a value to Numeric form.

 

 

Format

 

NUMERIC(expr)

 

where

 

expris the value to be converted.

 

 

The NUMERIC() function converts expr to numeric form, integer or floating point.

 

This function is rarely needed because all QMBasic operations requiring a numeric value perform the conversion automatically, however, if the value is used many times in a loop, there may be some performance advantage in converting it just once.

 

Traditionally multivalue Basic programs have performed this conversion by a statement of the form

N = X + 0

where the addition operator will convert the value of X to numeric form. The NUMERIC() function provides a neater and marginally more efficient way to do this.

 

 

Example

 

N = NUMERIC(X)

 

This statement converts X to numeric form.
