Description

These functions determine the minimum numeric value of their arguments. NaN arguments are treated as missing data: if one argument is a NaN and the other numeric, these functions choose the numeric value.

Return Values

Upon successful completion, these functions return the minimum numeric value of their arguments.

If just one argument is a NaN, the other argument is returned.

If x and y are NaN, a NaN is returned.

Errors

No errors are defined.
