Example 16 with BigDecimal

use of java.math.BigDecimal in project groovy by apache.

the class DefaultGroovyMethods method step.

/**
     * Iterates from this number up to the given number using a step increment.

     * <pre>0.step( 10, 2 ) {
     *   println it
     * }</pre>
     * Prints even numbers 0 through 8.

     * @param to         a Number to go up to, exclusive
     * @param stepNumber a Number representing the step increment
     * @param closure    the closure to call
