Results for &#x201C;Numeric parsing &amp; calculations&#x201D;

Compare small floating-point results with a tolerance

C: Use an absolute difference threshold for this known bounded magnitude.

Compute a two-dimensional vector length

C: hypot avoids unnecessary intermediate overflow compared with squaring both inputs directly.

Detect integer addition overflow

Java: Math.addExact throws rather than silently wrapping on overflow.

Display an integer as unsigned

Java: Use unsigned conversion methods when interpreting a fixed-width bit pattern.

Divide decimal values with controlled precision

Java: Choose both scale and rounding for a quotient that does not terminate in base ten.

Divide negative integers with floor rounding

Java: floorDiv and floorMod provide consistent floor-based quotient and remainder.

Find the greatest common divisor

Java: BigInteger.gcd calculates an exact nonnegative common divisor.

Parse an integer in another base

Java: Supply an explicit radix to Integer.parseInt.

Parse an unsigned hexadecimal integer

C: Use an explicit base and check both range and full consumption.

Reject NaN and infinite values

C: isfinite detects whether a floating-point value is an ordinary finite number.

Reject nonfinite floating-point values

Java: Double.isFinite excludes both infinity and NaN.

Round a decimal with an explicit rule

Java: Construct BigDecimal from text to avoid importing a binary floating-point approximation.
