If both px and py are Strings, then 9 ... 10 4. Else, 11 a. Let nx be ? ToNumeric(px). Because px and py are primitive values evaluation order is not important. 12 b. Let ny be ? ToNumeric(py). 13 c. If Type(nx) is Type(ny), return ? Type(nx)::lessThan(nx, ny). 14 d. Assert: Type(nx) is BigInt and Type(ny) is Number, or if Type(nx) is Number and Type(ny) is BigInt. 15 e. If x or y are any of NaN, return undefined. 16 f. If x is -∞, or y is +∞, return true. 17 g. If x is +∞, or y is -∞, return false. 18 h. If the mathematical value of nx is less than the mathematical value of ny, return true, otherwise return false. 19 features: [BigInt] 20 ---*/ 21 assert.sameValue(0n < 0, false, 'The result of (0n < 0) is false'); 22 assert.sameValue(0 < 0n, false, 'The result of (0 < 0n) is false'); 23 assert.sameValue(0n < -0, false, 'The result of (0n < -0) is false'); 24 assert.sameValue(-0 < 0n, false, 'The result of (-0 < 0n) is false'); 25 assert.sameValue(0n < 0.000000000001, true, 'The result of (0n < 0.000000000001) is true'); 26 assert.sameValue(0.000000000001 < 0n, false, 'The result of (0.000000000001 < 0n) is false'); 27 assert.sameValue(0n < 1, true, 'The result of (0n < 1) is true'); 28 assert.sameValue(1 < 0n, false, 'The result of (1 < 0n) is false'); 29 assert.sameValue(1n < 0, false, 'The result of (1n < 0) is false'); 30 assert.sameValue(0 < 1n, true, 'The result of (0 < 1n) is true'); 31 assert.sameValue(1n < 0.999999999999, false, 'The result of (1n < 0.999999999999) is false'); 32 assert.sameValue(0.999999999999 < 1n, true, 'The result of (0.999999999999 < 1n) is true'); 33 assert.sameValue(1n < 1, false, 'The result of (1n < 1) is false'); 34 assert.sameValue(1 < 1n, false, 'The result of (1 < 1n) is false'); 35 assert.sameValue(0n < Number.MIN_VALUE, true, 'The result of (0n < Number.MIN_VALUE) is true'); 36 assert.sameValue(Number.MIN_VALUE < 0n, false, 'The result of (Number.MIN_VALUE < 0n) is false'); 37 assert.sameValue(0n < -Number.MIN_VALUE, false, 'The result of (0n < -Number.MIN_VALUE) is false'); 38 assert.sameValue(-Number.MIN_VALUE < 0n, true, 'The result of (-Number.MIN_VALUE < 0n) is true'); 39 assert.sameValue(-10n < Number.MIN_VALUE, true, 'The result of (-10n < Number.MIN_VALUE) is true'); 40 41 assert.sameValue( 42 Number.MIN_VALUE < -10n, 43 false, 44 'The result of (Number.MIN_VALUE < -10n) is false' 45 ); 46 47 reportCompare(0, 0);
