cy.contains cant find element after calculations

[DeXoN0607]

Hi.
When I try to find an element by doing a preliminary calculation (withinSubject: true,):
const contribution = 10000000.01;
const survival = new Intl.NumberFormat().format(contribution);
....
cy.get('[class="parent-grid-12 ai-width-12"] tr[id="-row-0"]')
.find('[class="ai-output-text-bootstrap"]')
.should('be.visible')
.eq(1)
.contains(survival, {matchCase: false})
But I see this:

Try toLocaleString(). Same error.

If i type like this all works:
cy.get('[class="parent-grid-12 ai-width-12"] tr[id="-row-0"]')
.find('[class="ai-output-text-bootstrap"]')
.should('be.visible')
.eq(1)
.contains('10 000 000,01')

But i need to use calculation and find this element:
10 000 000,00

I new in cypress and JS. Sry, if my question is stupid
