| Fill in the blank to round up. | let roundedNum = ___________(numWithDecimal); | Math.ceil | Math\.ceil |
| What is the value of roundedNum? | let roundedNum = Math.floor(1.9); | 1 | 1 |
| Round up origNum and assign it to roundNum, which hasn't been declared beforehand. | let roundNum = Math.ceil(origNum); | letroundNum=Math\.ceil\(origNum\); | |
| Round down origNum and assign it to roundNum, which hasn't been declared beforehand. | let roundNum = Math.floor(origNum); | letroundNum=Math\.floor\(origNum\); | |
| Round a variable's number to the nearest integer. Assign the result to a second variable that hasn't been declared beforehand. Make up the variable names. | let newNum = Math.round(numWithDecimal); | let[a-z_$][a-zA-Z0-9_$]*=Math.round\([a-z_$][a-zA-Z0-9_$]*\); | |
| Round down a variable's number and assign the result to a second variable that hasn't been declared beforehand. Make up the variable names. | let newNum = Math.floor(numWithDecimal); | let[a-z_$][a-zA-Z0-9_$]*=Math\.floor\([a-z_$][a-zA-Z0-9_$]*\); | |
| Round up a variable's number and assign the result to a second variable that hasn't been declared beforehand. Make up the variable names. | let newNum = Math.ceil(fractional); | let[a-z_$][a-zA-Z0-9_$]*=Math\.ceil\([a-z_$][a-zA-Z0-9_$]*\); | |
| Round .00001 to 1 and assign it to a variable that hasn't been declared beforehand. Make up the variable name. | let num = Math.ceil(.00001); | let[a-z_$][a-zA-Z0-9_$]*=Math\.ceil\(\.00001\); | |
