zeroDecimalsInValue()

int pappso::Utils::zeroDecimalsInValue ( pappso_double value )

static

Determine the number of zero decimals between the decimal point and the first non-zero decimal.

0.11 would return 0 (no empty decimal) 2.001 would return 2 1000.0001254 would return 3

Parameters

value

the value to be analyzed

Returns

the number of '0' decimals between the decimal separator '.' and the first non-0 decimal
